fix: add automatic release workflow for tag-based releases

- Triggers on tag pushes (v*) to create GitHub releases
- Publishes Helm chart to OCI registry
- Generates release notes with commit history
- Complements existing build-and-push workflow

Now releases are fully automated:
1. Push tag → build-and-push.yaml builds Docker images
2. Push tag → release.yaml creates GitHub release + publishes Helm chart
