Launcher tweaks

- Handle beta/rc tags in .version when launching Anki
- Update pyproject.toml/.python_version if distributed version newer
- Support prerelease marker to opt in to betas
- Check for updates when using uv sync
- Avoid system Python by default, as it can cause breakages
(e.g. ARM Python installed on Windows)
