fix(ci): add GitHub Actions release workflows and fix visual test

- Add release.yml for manual npm publishing on GitHub Release
- Add release-canary.yml for automated canary releases (every 20 commits)
- Fix visual test template path (use homedir() instead of ~)
- Update visual test baselines
- Add sync-version.mjs script for version synchronization
- Add sync-version npm script to package.json

scripts/sync-version.mjs
