Add matching session caching and native codegen improvements

- Introduced a new matching session caching mechanism in the Lua matching module to enhance performance with native code generation.
- Rewrote the Lua matching algorithm to utilize session-based caching, reducing redundant computations and improving efficiency.
- Updated Rust implementations to include session caching, ensuring consistency across both Lua and Rust.
- Enhanced the `hydrate` function to support session management during instance hydration.
- Added comprehensive tests to validate the new caching mechanism and its integration with existing functionality.

These changes significantly improve the performance and maintainability of the matching process in the application.
