refactor: Migrate container management to heropods module

Browse Source 
- Remove `herorun` module and related scripts
- Introduce `heropods` module for container management
- Enhance `tmux` module with pane clearing and creation
- Update `Container` methods to use `osal.Command` result
- Improve `ContainerFactory` for image & container handling

# HeroRun - AI Agent Optimized Container Management
**Production-ready scripts for fast remote command execution**
## 🎯 Purpose
Optimized for AI agents that need rapid, reliable command execution with minimal latency and clean output.
## 🏗️ Base Image Types
HeroRun supports different base images through the `BaseImage` enum:
```v
pub enum BaseImage {
alpine // Standard Alpine Linux minirootfs (~5MB)
alpine_python // Alpine Linux with Python 3 pre-installed
}
```
### Usage Examples
**Standard Alpine Container:**
```v
base_image: .alpine // Default - minimal Alpine Linux
```
**Alpine with Python:**
```v
base_image: .alpine_python // Python 3 + pip pre-installed
```
## 📋 Three Scripts
### 1. `setup.vsh` - Environment Preparation
Creates container infrastructure on remote node.
```bash
./setup.vsh
```
**Output:** `Setup complete`
### 2. `execute.vsh` - Fast Command Execution
Executes commands on remote node with clean output only.
```bash
./execute.vsh "command" [context_id]
```
**Examples:**
```bash
./execute.vsh "ls /containers"
./execute.vsh "whoami"
./execute.vsh "echo 'Hello World'"
```
**Output:** Command result only (no verbose logging)
### 3. `cleanup.vsh` - Complete Teardown
Removes container and cleans up all resources.
```bash
./cleanup.vsh
```
**Output:** `Cleanup complete`
## ⚡ Performance Features
- **Clean Output**: Execute returns only command results
- **No Verbose Logging**: Silent operation for production use
- **Fast Execution**: Direct SSH without tmux overhead
- **AI Agent Ready**: Perfect for automated command execution
## 🚀 Usage Pattern
```bash
# Setup once
./setup.vsh
# Execute many commands (fast)
./execute.vsh "ls -la"
./execute.vsh "ps aux"
./execute.vsh "df -h"
# Cleanup when done
./cleanup.vsh
```
## 🎯 AI Agent Integration
Perfect for AI agents that need:
- Rapid command execution
- Clean, parseable output
- Minimal setup overhead
- Production-ready reliability
Each execute call returns only the command output, making it ideal for AI agents to parse and process results.
