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
