feat: migrate workflows to kcl-ci standard

- Add .forgejo/kcl-ci/ with kcl.mod, main.k, Taskfile.yaml
- claude.yml: use claude.k module (fixes #comment YAML validation error,
  removes duplicate pull_request_comment trigger)
- ci.yml: add paths-ignore for kcl-ci paths, named jobs for check constants
- test-action.yml: regenerated from KCL (functionally identical)
- upstream-sync.yml: regenerated from KCL (functionally identical)
- kcl-ci-build.yml: new auto-regeneration workflow (waits for CI checks)
