feat: cache VS Code Marketplace version badge via Gist (#88)

Replace the unreliable vsmarketplacebadges.dev badge with a shields.io
endpoint badge that reads from a GitHub Gist JSON file. The release
workflow now writes the version to the same Gist used for coverage,
so the badge never hits a flaky third-party service.

- Add version extraction and dynamic-badges-action step to release.yml
- Update README badge URL to use Gist endpoint
- Remove vsmarketplacebadges.dev from lychee exclude list
- Seed Gist with initial version.json for v0.0.1
