Refactor to use Rhai packages for efficient engine creation

- Created OsirisPackage with all OSIRIS types and functions registered in the package
- Functions now registered directly in package module (Note, Event, get_context)
- Created ZdfzPackage extending OsirisPackage
- Engine factory pattern: creates Engine::new_raw() + registers package (very cheap)
- Removed TypeRegistry (unused code)
- Simplified runner to use factory functions instead of passing packages
- Package is created once, then factory efficiently creates engines on demand

# OSIRIS Type Registry Design
## Problem
We need applications (like ZDFZ API) to register custom types with OSIRIS so that:
1. The `save()` method can use the correct struct type instead of hardcoding `Note`
2. Each collection name maps to a specific Rust type
3. The type system properly deserializes, indexes, and stores data
## Challenge
The `Object` trait is not "dyn compatible" (object-safe) because it has:
- Associated functions (`object_type()`, `from_json()`)
- Generic methods
- Serialize/Deserialize bounds
This means we **cannot** use `Box<dyn Object>` for dynamic dispatch.
## Solution: Type Registry with Callbacks
Instead of trying to return `Box<dyn Object>`, we use a callback-based approach:
```rust
pub struct TypeRegistry {
// For each collection, store a function that:
// 1. Takes JSON string
// 2. Deserializes to the correct type
// 3. Stores it using GenericStore
// 4. Returns the ID
savers: HashMap<String, Box<dyn Fn(&GenericStore, &str, &str) -> Result<()>>>,
}
```
### Usage in ZDFZ API:
```rust
// Create registry
let registry = TypeRegistry::new();
// Register Resident type
registry.register_saver("residents", |store, id, json| {
let mut resident: Resident = serde_json::from_str(json)?;
resident.set_id(id);
store.put(&resident).await
});
// Register Company type
registry.register_saver("companies", |store, id, json| {
let mut company: Company = serde_json::from_str(json)?;
company.set_id(id);
store.put(&company).await
});
// Create OSIRIS context with registry
let ctx = OsirisContext::new_with_registry(
"my_context",
"owner_id",
herodb_url,
db_id,
Some(Arc::new(registry))
);
// Now save() uses the registered type!
ctx.save("residents", "id123", resident_json)?;
```
### Benefits:
**Type-safe** - Each collection uses its proper Rust type
**Flexible** - Applications register their own types
**No trait object issues** - Uses closures instead of `Box<dyn Object>`
**Proper indexing** - Each type's `index_keys()` method is called
**Clean API** - Simple registration interface
## Implementation Plan:
1. ✅ Create `TypeRegistry` with callback-based savers
2. ✅ Add `set_registry()` to `GenericStore`
3. ✅ Update `OsirisContext::save()` to use registry if available
4. ✅ Fall back to `Note` if no registry or collection not registered
5. Document usage for ZDFZ API
## Next Steps:
The type registry infrastructure is in place. Now ZDFZ API can:
1. Create a `TypeRegistry`
2. Register all SDK model types
3. Pass registry when creating OSIRIS contexts
4. Use generic `save()` method with proper types!
---
**Status:** Design complete, ready for implementation with callback approach.
