Prepare 0.1.0 for lab release: durable handlers, HTTP Compose, CI, and pulumi-tests.

- Harden DB-backed handlers and seed profiles; align client wire shapes for
  cluster resources, QEMU config, and node SSL fields
- Serve plain HTTP on Compose :8006; keep TLS optional (--profile tls) and
  terminate HTTPS at Kubernetes Ingress
- Add pulumi-tests (full contract surface majors 6–9 + BPG lifecycle) and
  make pulumi-tests
- Ship bilingual docs, CHANGELOG, SECURITY, CONTRIBUTING, and GitHub Actions
  (make ci + Compose/Helm validation)

+  **8.4.5**, and **9.2.3** with full handler registration for declared methods.
+- Interactive Web UI (catalog, runtime contract Apply, task monitor).
+- Development Compose stack with plain HTTP on host `:8006` (real PVE port; real
+  PVE uses HTTPS). Optional TLS gateway via `--profile tls` on `:8443`.
+- Published runtime image workflow (`make release`) for
+  [`inecs/proxmox-api-simulator`](https://hub.docker.com/r/inecs/proxmox-api-simulator).
+- `docker-compose.release.yml` + Helm chart with optional Ingress / cert-manager.
+- Bilingual documentation (English + Russian) and client cookbooks.
