- Updated the NominatimRateLimiter to ensure thread-safe request recording and management.
- Refactored the wait_for_request and wait_and_request methods to share a single reservation mechanism for both async and sync callers.
- Enhanced the rate-limited geocoding functions to utilize the new request reservation method, ensuring proper request handling without unnecessary recording.
- Added tests to verify the correct behavior of the new request handling logic and its interaction between async and sync contexts.
- Added a tracked `LICENSE` file and updated `pyproject.toml` to include license metadata.
- Enhanced `CHANGELOG.md` with recent changes and clarifications.
- Updated `config.ini.example` and related documentation to reflect clamping behavior for numeric limits in `[Feed_Manager]`.
- Improved startup validation to suggest corrections for unknown and misspelled keys.
- Refactored geocoding and HTTP request handling to run off-thread, preventing event loop stalls.
- Added thread safety to cache management in geocoding functions to avoid race conditions.
