Bootstrap apps/collab as a Hocuspocus WebSocket server (ADR 0003): - pino JSON logging (service=collab) and shared Zod env validation (collabEnvSchema); structured connection open/close logs. - /healthz endpoint (process liveness + PostgreSQL ping) served via the onRequest hook, matching the container-internal path and the proxied /collab/healthz path; any WebSocket handshake is accepted for now (authentication arrives with #34, persistence with #35). - Dockerfile (ESM workspace build) and a compose service on the frontend and internal networks with a healthcheck; dev overlay service and a new COLLAB_PORT variable. - CD builds, pushes, and promotes the collab image; CI builds it on PRs; the smoke suite asserts /collab/healthz through the reverse proxy. - deployment.md/stages.md: proxy routing, per-stage COLLAB_PORT, checklist.
