Refactor logging and configuration handling across multiple modules

- Removed unused logging functions in `logging.rs` to streamline the code.
- Updated session management in `session_manager.rs` by renaming a variable for clarity.
- Refactored command handling in `config.rs` to use `first()` instead of `get(0)` for better readability.
- Cleaned up unused constants and improved struct definitions in `daemon-manager` and `mcp` modules.
- Enhanced error handling and logging consistency across various files, improving overall code maintainability.
