chore: release version 2.4.0 with unique text constraint and conflict handling

- Added `unique_text` parameter in `create_table` for enforcing uniqueness on the text column.
- Introduced `on_conflict` parameter in `add` method to manage duplicate entries with options: "error", "ignore", and "replace".
- Implemented validation for `on_conflict` values to ensure only accepted options are used.
- Updated tests to cover unique text constraints and all conflict resolution strategies.
- Updated version in `pyproject.toml` and added `uv.lock` file.
