Migrate to uv and add GitHub CI workflow (#4)

* Migrate from Poetry to uv and add CI pipeline

- Convert pyproject.toml from Poetry to standard PEP 621 format
- Add pytest as a dev dependency
- Create basic test structure with initial tests
- Add GitHub Actions CI workflow that runs pytest on Python 3.8
- Remove poetry.lock and add uv.lock to .gitignore
- CI runs on ubuntu, windows, and macos to ensure cross-platform compatibility

* Disable uv cache in CI workflow

Since uv.lock is not committed to the repository, the cache option
should be disabled to avoid build failures.

* Skip project installation in CI workflow

This is a Sublime Text plugin, not a traditional Python package,
so we use --no-install-project flag to only install dependencies
without trying to install the project itself.
