feat: Add GitHub Actions for automated Docker image builds
Add comprehensive CI/CD pipeline for building and publishing Docker images
to GitHub Container Registry (ghcr.io).
Components:
- build-and-push.yaml: Main workflow for building and pushing images
- Triggers on push to main, tags, PRs, and manual dispatch
- Multi-tag strategy (latest, semver, sha, branch)
- Docker buildx with layer caching
- Automatic GHCR authentication
- Platform: linux/amd64
- release.yaml: Automated GitHub releases on version tags
- Auto-generates release notes from commits
- Creates GitHub release with Docker pull command
- dependabot.yml: Automated dependency updates
- Weekly updates for GitHub Actions
- Weekly updates for Docker base images
- PULL_REQUEST_TEMPLATE.md: PR template with testing checklist
Updated README:
- Add build status badge
- Update image pull instructions
- Reference automated builds
Image tagging strategy:
- main branch → :latest, :main, :main-{sha}
- v1.2.3 tag → :v1.2.3, :1.2, :1, :latest
- PR → :pr-{number}

### 1. Get the Image
|
||||
|
||||
The image is automatically built and published to GitHub Container Registry on every push to main.
|
||||
|
||||
```bash
|
||||
docker build -t ghcr.io/cpfarhood/antigravity:latest .

docker push ghcr.io/cpfarhood/antigravity:latest
