v2.0.0-alpha: BooCoder foundation — container, schema, DB rename

Phase 1 of v2.0. BooCoder is live at port 9502 with a health endpoint.

- Database renamed: ALTER DATABASE boocode RENAME TO boochat (one-time).
  All services updated to connect to /boochat. Docker service name stays
  boocode_db (rename is internal to Postgres, not Docker).

- New apps/coder/ app skeleton: Fastify server with health endpoint,
  postgres connection, schema apply on boot. Mirrors apps/server pattern
  but minimal (no inference loop yet — Phase 2).

- Schema: pending_changes (operation queue before /apply), tasks (dispatch
  DAG with state machine), available_agents (startup-probed agent registry),
  human_inbox view (tasks WHERE state IN blocked/failed). All IF NOT EXISTS,
  idempotent on re-run. Same boochat database, different tables.

- Dockerfile: Node 20 bookworm-slim (glibc for future node-pty in Phase 5).
  Multi-stage build matching the existing boocode image pattern.

- docker-compose.yml: boocoder service on 100.114.205.53:9502, /opt:/opt:rw
  mount (write-capable, policy-gated at tool layer), depends on boocode_db.

- BOOCODER.md: container guidance declaring write-tool capability +
  pending-changes discipline.

All 4 services boot and pass health checks. 9 tables in the shared DB.
