feat: add CI/release automation and complete SDK implementation

- Add Forgejo CI workflow: gofmt checks, module caching, coverage reporting
- Add release workflow: auto-tag-triggered release with changelog extraction
- Update module paths from rock/ to homelab/ namespace
- Enhance test coverage and documentation (PLAN.md, README.md)
