🤖 feat: implement trunk-based CI/CD with local testing

- Designed trunk-based development workflow with branch protection
- Added workflow validation job to prevent main branch breaks
- Integrated act (GitHub Actions runner) for local Gitea workflow testing
- Created unified CI/CD script interface (scripts/cicd.sh)
- Added YAML lint configuration with practical limits (400 chars)
- Organized all CI/CD scripts under scripts/cicd/ directory
- Confirmed Gitea/GitHub Actions compatibility via local testing
- Updated ADR 0017 with implementation details and test results
- Enhanced documentation with local development workflow

See ADR-0017 for complete trunk-based development workflow documentation.
See ADR-0016 for CI/CD pipeline design.
