Mark T01 done after pushing gitea.coulomb.social/coulomb/issue-core:0.2.0. Update workplan state and note platform bootstrap dependency for T02/T04.
Introduce Dockerfile, entrypoint, and k8s/railiance manifests for the ArgoCD GitOps pilot (ISSUE-WP-0003). Rename the Gitea PyPI build arg to GITEA_PYPI_INDEX_URL so pip still resolves dependencies from PyPI.
