feat: add automatic release checking and creation

- Add --check-releases flag for manual release checking
- Enable automatic release checking after sync operations by default
- Add --no-check-releases flag to disable automatic checking
- Add --auto-create-releases flag for unattended release creation
- Generate release notes from commit history
- Support version tag formats: vX.Y.Z, vX.Y, vX, X.Y.Z, X.Y, X
- Use tokens from gitsyncer config (with fallback to env vars and files)
- Show release notes preview before creating releases
- Group commits by type (features, fixes, other) in release notes
