initial scaffold: emdash catalog, helm chart, woodpecker pipeline, ddev

- app/: Emdash scaffold (Astro 6, node target) with cmses/plugins/pages collections
- app/seed/seed.json: WordPress→Emdash parity for kotkanagrilli.fi (~30 entries)
- Dockerfile + docker/entrypoint.sh: multi-stage build, single PVC at /app/state
- deploy/helm/: chart mirroring emdash-kotkanagrilli (single-replica, sqlite, kotkan)
- deploy/fleet-overlay/: HelmRelease/source/image-automation templates for
  anton-helm-workloads (staging + production)
- .woodpecker/container.yaml: arm64 build, three OCI tags per push
  (immutable 0.1.<pipeline> + floating <branch> + <branch>-latest)
- .ddev/: local dev with nginx proxy to emdash on :4321
- README/DEPLOYMENT/ARCHITECTURE/CLAUDE: docs covering the three-repo
  pipeline (cms-plugins + anton-helm-workloads + Gitea OCI registry)
