fix: Address code review issues with minimal changes

- Remove unused imports (json, List, get_session_from_context)
- Fix event loop handling to avoid conflicts with existing loops
- Add TypeScript interface for tool definitions instead of using any
- Update receive methods to return placeholder instead of throwing errors
- Simplify transport detection logic by removing unnecessary elif
- Add finally block to ensure init_done.set() is always called

These changes maintain backward compatibility while fixing the critical
runtime issues identified in the code review.
