Subject: [PATCH] Build forgejo-runner container locally (#334)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary
- Add native Dagger `container.py` for forgejo-runner (Go + Alpine runtime, static binary with CGO for SQLite)
- Update kustomization to point to local registry image (tag is placeholder until CI builds)
- Uses existing `clone_from_forge("forgejo-runner", ...)` mirror

## Test plan
- [x] `dagger call build --src=. --container-name=forgejo-runner` passes locally
- [ ] CI container build from branch succeeds
- [ ] Update kustomization tag to built image, deploy from branch via ArgoCD `--revision`
- [ ] Verify runner registers and picks up jobs
