remove ts extension

- Added SignRequestManager.js to manage sign requests, including UI states for keyspace lock, mismatch, and approval.
- Implemented methods for loading state, rendering UI, and handling user interactions (approve/reject requests).
- Integrated background message listeners for keyspace unlock events and request updates.

+## What is Rust Conditional Compilation?
+
+Rust's conditional compilation allows you to write code that only gets included for certain platforms or configurations. This is done using attributes like `#[cfg(target_arch = "wasm32")]` for WebAssembly, or `#[cfg(not(target_arch = "wasm32"))]` for native platforms. It enables a single codebase to support multiple targets (such as desktop and browser) with platform-specific logic where needed.
+
+**Example:**
+```rust
+#[cfg(target_arch = "wasm32")]
+// This code only compiles for WebAssembly targets
+```
+
+## What is WASM (WebAssembly)?
+
+WebAssembly (WASM) is a binary instruction format for a stack-based virtual machine. It allows code written in languages like Rust, C, or C++ to run at near-native speed in web browsers and other environments. In this project, WASM enables the cryptographic vault to work securely inside the browser, exposing Rust functions to JavaScript and web applications.

+
+## Conditional Compilation & WASM Support
+
+This project makes extensive use of Rust's conditional compilation to support both native and WebAssembly (WASM) environments with a single codebase. Key points:
+
+- **Platform-specific code:**
+  - Rust's `#[cfg(target_arch = "wasm32")]` attribute is used to write WASM-specific code, while `#[cfg(not(target_arch = "wasm32"))]` is for native targets.
+  - This pattern is used for struct definitions, method implementations, and even module imports.
+
+- **Example: SessionManager**
+  ```rust
+  #[cfg(not(target_arch = "wasm32"))]
+  pub struct SessionManager<S: KVStore + Send + Sync> { ... }
+
+  #[cfg(target_arch = "wasm32")]
+  pub struct SessionManager<S: KVStore> { ... }
+  ```
+
+- **WASM Bindings:**
+  - The `wasm_app` crate uses `wasm-bindgen` to expose Rust functions to JavaScript, enabling browser integration.
+  - Functions are annotated with `#[wasm_bindgen]` and exported for use in JS/TS.
+
+- **Storage Backends:**
+  - Native uses `sled` or other file-based stores.
+  - WASM uses IndexedDB (via `kvstore::wasm::WasmStore`).
+
+- **Building for WASM:**
+  - Use `wasm-pack build --target web` to build the WASM package.
+  - Serve the resulting files with a static server for browser use.
+
+- **Testing:**
+  - Both native and WASM tests are supported. WASM tests can be run in headless browsers using `wasm-pack test --headless --firefox` or similar commands.

+# Mock SigSocket Server Demo
+
+This directory contains a mock SigSocket server for testing the browser extension functionality.
+
+## Setup
+
+1. Install dependencies:
+   ```bash
+   npm install
+   ```
+
+2. Start the mock server:
+   ```bash
+   npm start
+   ```
+
+The server will listen on `ws://localhost:8080/ws`
+
+## Usage
+
+### Interactive Commands
+
+Once the server is running, you can use these commands:
+
+- `test` - Send a test sign request to all connected clients
+- `status` - Show server status and connected clients
+- `quit` - Shutdown the server
+
+### Testing Flow
+
+1. Start the mock server
+2. Load the browser extension in Chrome
+3. Create a keyspace and keypair in the extension
+4. The extension should automatically connect to the server
+5. The server will send a test sign request after 3 seconds
+6. Use the extension popup to approve or reject the request
+7. The server will log the response and send another request after 10 seconds
+
+### Expected Output
+
+When a client connects:
+```
+New WebSocket connection from: ::1
+Received message: 04a8b2c3d4e5f6...
+Client registered: client_1234567890_abc123 with public key: 04a8b2c3d4e5f6...
+📝 Sending sign request to client_1234567890_abc123: req_1_1234567890
+   Message: "Test message 1 - 2024-01-01T12:00:00.000Z"
+```
+
+When a sign response is received:
+```
+Received sign response from client_1234567890_abc123: {
+  id: 'req_1_1234567890',
+  message: 'VGVzdCBtZXNzYWdlIDEgLSAyMDI0LTAxLTAxVDEyOjAwOjAwLjAwMFo=',
+  signature: '3045022100...'
+}
+✅ Sign request req_1_1234567890 completed successfully
+   Signature: 3045022100...
+```
+
+## Protocol
+
+The mock server implements a simplified version of the SigSocket protocol:
+
+1. **Client Introduction**: Client sends hex-encoded public key
+2. **Welcome Message**: Server responds with welcome JSON
+3. **Sign Requests**: Server sends JSON with `id` and `message` (base64)
+4. **Sign Responses**: Client sends JSON with `id`, `message`, and `signature`
+
+## Troubleshooting
+
+- **Connection refused**: Make sure the server is running on port 8080
+- **No sign requests**: Check that the extension is properly connected
+- **Extension errors**: Check the browser console for JavaScript errors
+- **WASM errors**: Ensure the WASM files are properly built and loaded

+# Testing the SigSocket Browser Extension
+
+## Prerequisites
+
+1. **SigSocket Server**: You need a running SigSocket server at `ws://localhost:8080/ws`
+2. **Browser**: Chrome or Chromium-based browser with developer mode enabled
+
+## Test Steps
+
+### 1. Load the Extension
+
+1. Open Chrome and go to `chrome://extensions/`
+2. Enable "Developer mode" in the top right
+3. Click "Load unpacked" and select the `crypto_vault_extension` directory
+4. The CryptoVault extension should appear in your extensions list
+
+### 2. Basic Functionality Test
+
+1. Click the CryptoVault extension icon in the toolbar
+2. Create a new keyspace:
+   - Enter a keyspace name (e.g., "test-workspace")
+   - Enter a password
+   - Click "Create New"
+3. The extension should automatically connect to the SigSocket server
+4. Add a keypair:
+   - Click "Add Keypair"
+   - Enter a name for the keypair
+   - Click "Create Keypair"
+
+### 3. SigSocket Integration Test
+
+1. **Check Connection Status**:
+   - Look for the SigSocket connection status at the bottom of the popup
+   - It should show "SigSocket: Connected" with a green indicator
+
+2. **Test Sign Request Flow**:
+   - Send a sign request to the SigSocket server (you'll need to implement this on the server side)
+   - The extension should show a notification
+   - The extension badge should show the number of pending requests
+   - Open the extension popup to see the sign request
+
+3. **Test Approval Flow**:
+   - If keyspace is locked, you should see "Unlock keyspace to see X pending requests"
+   - Unlock the keyspace using the login form
+   - You should see the sign request details
+   - Click "Approve & Sign" to approve the request
+   - The request should be signed and sent back to the server
+
+### 4. Settings Test
+
+1. Click the settings gear icon in the extension popup
+2. Change the SigSocket server URL if needed
+3. Adjust the session timeout if desired
+
+## Expected Behavior
+
+- ✅ Extension loads without errors
+- ✅ Can create keyspaces and keypairs
+- ✅ SigSocket connection is established automatically
+- ✅ Sign requests are received and displayed
+- ✅ Approval flow works correctly
+- ✅ Settings can be configured
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Extension won't load**: Check the console for JavaScript errors
+2. **SigSocket won't connect**: Verify the server is running and the URL is correct
+3. **WASM errors**: Check that the WASM files are properly built and copied
+4. **Sign requests not appearing**: Check the browser console for callback errors
+
+### Debug Steps
+
+1. Open Chrome DevTools
+2. Go to the Extensions tab
+3. Find CryptoVault and click "Inspect views: background page"
+4. Check the console for any errors
+5. Also inspect the popup by right-clicking the extension icon and selecting "Inspect popup"
+
+## Server-Side Testing
+
+To fully test the extension, you'll need a SigSocket server that can:
+
+1. Accept WebSocket connections at `/ws`
+2. Handle client introduction messages (hex-encoded public keys)
+3. Send sign requests in the format:
+
+   ```json
+   {
+     "id": "unique-request-id",
+     "message": "base64-encoded-message"
+   }
+   ```
+
+4. Receive sign responses in the format:
+
+   ```json
+   {
+     "id": "request-id",
+     "message": "base64-encoded-message",
+     "signature": "base64-encoded-signature"
+   }
+   ```
+
+## Next Steps
+
+If basic functionality works:
+
+1. Test with multiple concurrent sign requests
+2. Test connection recovery after network issues
+3. Test with different keyspace configurations
+4. Test the rejection flow
+5. Test session timeout behavior

-# Modular Vault Browser Extension
-
-A cross-browser (Manifest V3) extension for secure cryptographic operations and Rhai scripting, powered by Rust/WASM.
-
-## Features
-- Session/keypair management
-- Cryptographic signing, encryption, and EVM actions
-- Secure WASM integration (signing only accessible from extension scripts)
-- React-based popup UI with dark mode
-- Future: WebSocket integration for remote scripting
-
-## Structure
-- `manifest.json`: Extension manifest (MV3, Chrome/Firefox)
-- `popup/`: React UI for user interaction
-- `background/`: Service worker for session, keypair, and WASM logic
-- `assets/`: Icons and static assets
-
-## Dev Workflow
-1. Build Rust WASM: `wasm-pack build --target web --out-dir ../extension/wasm`
-2. Install JS deps: `npm install` (from `extension/`)
-3. Build popup: `npm run build`
-4. Load `/extension` as an unpacked extension in your browser
-
----
-
-## Security
-- WASM cryptographic APIs are only accessible from extension scripts (not content scripts or web pages).
-- All sensitive actions require explicit user approval.
-
----
-
-## TODO
-- Implement background logic for session/keypair
-- Integrate popup UI with WASM APIs
-- Add WebSocket support (Phase 2)

+# SigSocket Client Implementation
+
+## Overview
+
+This document describes the implementation of the `sigsocket_client` crate, a WebSocket client library designed for connecting to sigsocket servers with **WASM-first support**.
+
+## Architecture
+
+### Core Design Principles
+
+1. **WASM-First**: Designed primarily for browser environments with native support as a secondary target
+2. **No Signing Logic**: The client delegates all signing operations to the application
+3. **User Approval Flow**: Applications are notified about incoming requests and handle user approval
+4. **Protocol Compatibility**: Fully compatible with the sigsocket server protocol
+5. **Async/Await**: Modern async Rust API throughout
+
+### Module Structure
+

+│   └── wasm_usage.rs    # WASM usage example
+├── tests/
+│   └── integration_test.rs
+└── README.md
+```
+
+## Protocol Implementation
+
+The sigsocket protocol is simple and consists of three message types:
+
+### 1. Introduction Message
+When connecting, the client sends its public key as a hex-encoded string:
+```
+02f9308a019258c31049344f85f89d5229b531c845836f99b08601f113bce036f9
+```
+
+### 2. Sign Request (Server → Client)
+```json
+{
+  "id": "req_123",
+  "message": "dGVzdCBtZXNzYWdl"  // base64-encoded message
+}
+```
+
+### 3. Sign Response (Client → Server)
+```json
+{
+  "id": "req_123",
+  "message": "dGVzdCBtZXNzYWdl",  // original message
+  "signature": "c2lnbmF0dXJl"      // base64-encoded signature
+}
+```
+
+## Key Features Implemented
+
+### ✅ Dual Platform Support
+- **Native**: Uses `tokio` and `tokio-tungstenite` for async WebSocket communication
+- **WASM**: Uses `web-sys` and `wasm-bindgen` for browser WebSocket API
+
+### ✅ Type-Safe Protocol
+- `SignRequest` and `SignResponse` structs with serde serialization
+- Helper methods for base64 encoding/decoding
+- Comprehensive error handling
+
+### ✅ Flexible Sign Handler Interface
+```rust
+trait SignRequestHandler {
+    fn handle_sign_request(&self, request: &SignRequest) -> Result<Vec<u8>>;
+}
+```
+
+### ✅ Connection Management
+- Automatic connection state tracking
+- Clean disconnect handling
+- Connection status queries
+
+### ✅ Error Handling
+- Comprehensive error types for different failure modes
+- Platform-specific error conversions
+- WASM-compatible error handling (no `std::error::Error` dependency)
+
+## Platform-Specific Implementations
+
+### Native Implementation (`native.rs`)
+- Uses `tokio-tungstenite` for WebSocket communication
+- Spawns separate tasks for reading and writing
+- Thread-safe with `Arc<RwLock<T>>` for shared state
+- Supports `Send + Sync` trait bounds
+
+### WASM Implementation (`wasm.rs`)
+- Uses `web-sys::WebSocket` for browser WebSocket API
+- Event-driven with JavaScript closures
+- Single-threaded (no `Send + Sync` requirements)
+- Browser console logging for debugging
+
+## Usage Patterns
+
+### Native Usage
+```rust
+#[tokio::main]
+async fn main() -> Result<()> {
+    let public_key = hex::decode("02f9308a...")?;
+    let mut client = SigSocketClient::new("ws://localhost:8080/ws", public_key)?;
+    
+    client.set_sign_handler(MySignHandler);
+    client.connect().await?;
+    
+    // Client handles requests automatically
+    Ok(())
+}
+```
+
+### WASM Usage
+```rust
+#[wasm_bindgen]
+pub async fn connect_to_sigsocket() -> Result<(), JsValue> {
+    let public_key = get_user_public_key()?;
+    let mut client = SigSocketClient::new("ws://localhost:8080/ws", public_key)?;
+    
+    client.set_sign_handler(WasmSignHandler);
+    client.connect().await?;
+    
+    Ok(())
+}
+```
+
+## Testing
+
+### Unit Tests
+- Protocol message serialization/deserialization
+- Error handling and conversion
+- Client creation and configuration
+
+### Integration Tests
+- End-to-end usage patterns
+- Sign request/response cycles
+- Error scenarios
+
+### Documentation Tests
+- Example code in documentation is verified to compile
+
+## Dependencies
+
+### Core Dependencies (Both Platforms)
+- `serde` + `serde_json` - JSON serialization
+- `hex` - Hex encoding/decoding
+- `base64` - Base64 encoding/decoding
+- `url` - URL parsing and validation
+
+### Native-Only Dependencies
+- `tokio` - Async runtime
+- `tokio-tungstenite` - WebSocket client
+- `futures-util` - Stream utilities
+- `thiserror` - Error derive macros
+
+### WASM-Only Dependencies
+- `wasm-bindgen` - Rust/JavaScript interop
+- `web-sys` - Browser API bindings
+- `js-sys` - JavaScript type bindings
+- `wasm-bindgen-futures` - Async support
+
+## Build Targets
+
+### Native Build
+```bash
+cargo build --features native
+cargo test --features native
+cargo run --example basic_usage --features native
+```
+
+### WASM Build
+```bash
+cargo check --target wasm32-unknown-unknown --features wasm
+wasm-pack build --target web --features wasm
+```
+
+## Future Enhancements
+
+### Potential Improvements
+1. **Reconnection Logic**: Automatic reconnection with exponential backoff
+2. **Request Queuing**: Queue multiple concurrent sign requests
+3. **Timeout Handling**: Configurable timeouts for requests
+4. **Metrics**: Connection and request metrics
+5. **Logging**: Structured logging with configurable levels
+
+### WASM Enhancements
+1. **Better Callback System**: More ergonomic callback handling in WASM
+2. **Browser Wallet Integration**: Direct integration with MetaMask, etc.
+3. **Service Worker Support**: Background request handling
+
+## Security Considerations
+
+1. **No Private Key Storage**: The client never handles private keys
+2. **User Approval Required**: All signing requires explicit user approval
+3. **Message Validation**: All incoming messages are validated
+4. **Secure Transport**: Requires WebSocket Secure (WSS) in production
+
+## Compatibility
+
+- **Rust Version**: 1.70+
+- **WASM Target**: `wasm32-unknown-unknown`
+- **Browser Support**: Modern browsers with WebSocket support
+- **Server Compatibility**: Compatible with sigsocket server protocol
+
+This implementation provides a solid foundation for applications that need to connect to sigsocket servers while maintaining security and user control over signing operations.

+        
+    Ok(())
+}
+```
+
+## Protocol
+
+The sigsocket client implements a simple WebSocket protocol:
+
+### 1. Introduction
+Upon connection, the client sends its public key as a hex-encoded string:
+```
+02f9308a019258c31049344f85f89d5229b531c845836f99b08601f113bce036f9388
+```
+
+### 2. Sign Requests
+The server sends signature requests as JSON:
+```json
+{
+  "id": "req_123",
+  "message": "dGVzdCBtZXNzYWdl"  // base64-encoded message
+}
+```
+
+### 3. Sign Responses  
+The client responds with signatures as JSON:
+```json
+{
+  "id": "req_123",
+  "message": "dGVzdCBtZXNzYWdl",  // original message
+  "signature": "c2lnbmF0dXJl"      // base64-encoded signature
+}
+```

+//! # SigSocket Client
+//!
+//! A WebSocket client library for connecting to sigsocket servers with WASM-first support.
+//!
+//! This library provides a unified interface for both native and WASM environments,
+//! allowing applications to connect to sigsocket servers using a public key and handle
+//! incoming signature requests.
+//!
+//! ## Features
+//!
+//! - **WASM-first design**: Optimized for browser environments
+//! - **Native support**: Works in native Rust applications
+//! - **No signing logic**: Delegates signing to the application
+//! - **User approval flow**: Notifies applications about incoming requests
+//! - **sigsocket compatible**: Fully compatible with sigsocket server protocol
+//!
+//! ## Example
+//!
+//! ```rust,no_run
+//! use sigsocket_client::{SigSocketClient, SignRequest, SignRequestHandler, Result};
+//!
+//! struct MyHandler;
+//! impl SignRequestHandler for MyHandler {
+//!     fn handle_sign_request(&self, _request: &SignRequest) -> Result<Vec<u8>> {
+//!         Ok(b"fake_signature".to_vec())
+//!     }
+//! }
+//!
+//! #[tokio::main]
+//! async fn main() -> Result<()> {
+//!     // Create client with public key
+//!     let public_key = hex::decode("02f9308a019258c31049344f85f89d5229b531c845836f99b08601f113bce036f9").unwrap();
+//!     let mut client = SigSocketClient::new("ws://localhost:8080/ws", public_key)?;
+//!
+//!     // Set up request handler
+//!     client.set_sign_handler(MyHandler);
+//!
+//!     // Connect to server
+//!     client.connect().await?;
+//!     Ok(())
+//! }
+//! ```
