- Add GitHub Actions workflow for building and publishing packages.
- Introduce `pyproject.toml` for project metadata and dependency management.
- Remove `requirements.txt` in favor of Poetry for dependency handling.
- Restructure source files under `src/pyvtt` for better organization.
- Enhance `notify.py` with sound playback and improve error handling.
- Update `voice_to_text_tray.py` to support dynamic configuration reload.
- Add `.vscode/settings.json` for improved IDE configuration.
- Update `.gitignore` to exclude build artifacts.
