- Updated the `resolve_path` function in `utils.py` to clarify behavior regarding absolute paths. - Changed type hints in `discord_bridge_service.py` for better clarity and consistency. - Removed unused imports and unnecessary comments in various test files to improve code cleanliness and readability.
