Update BaseLM.get_last_usage type hint to return ModelUsageSummary, reflecting actual client implementations.
Wrap atomic usage stats in UsageSummary within LMHandler to satisfy RLMChatCompletion type expectations and ensure consistent serialization structure.

* feat: add Daytona REPL environment support

- Introduced a new Daytona REPL environment for executing Python code in Daytona sandboxes.
- Updated `pyproject.toml` to include `daytona` as an optional dependency.
- Added example usage of Daytona REPL in `examples/daytona_repl_example.py`.
- Modified existing code to support the new `daytona` environment in `rlm/environments/__init__.py` and `rlm/core/types.py`.
- Enhanced the `RLM` initialization in `examples/quickstart.py` to utilize the Daytona environment.

This implementation allows users to run code in isolated Daytona sandboxes, facilitating LLM queries and state management.

* feat: enhance Daytona REPL examples and documentation

* revert quickstart.py

* fixed merge conflict

* updated daytona repl to take the right default key

* updated example
