feat(ops+workplans): fix tunnel targets, plan custodian migration, close legacy ADR-001 gaps

Tunnel (state-hub/Makefile):
- Replace interactive `make tunnel` (now non-blocking with -N flag)
- Add tunnel-daemon (autossh background), tunnel-loop (reconnect fallback),
  tunnel-status, tunnel-stop
- Default COULOMBCORE=tegwick@92.205.130.254; TUNNEL_PORT configurable
- Clarified server topology: COULOMBCORE=92.205.130.254 (old),
  Railiance01=92.205.62.239 (ThreePhoenix node 1)

Workplans:
- CUST-WP-0011: Migrate Custodian State Hub to ThreePhoenix cluster —
  9-task plan with hard pre-condition gates (3-node cluster, Longhorn HA,
  backup drill), data migration, 2-week stabilisation, WSL2 retirement
- CUST-WP-0000: Retroactive record for state-hub v0.1 (pre-ADR-001)
- CUST-WP-0000b: Retroactive record for state-hub v0.2 (pre-ADR-001)

Consistency: repo now ✓ PASS (0 fail, 18 warn — all pre-ADR-001 C-12 history)

+- FastAPI app with routers for all entities + `/state/summary`
+- FastMCP stdio server (11 tools, 5 resources/templates)
+- Observable Framework dashboard (4 pages: index, workstreams, decisions, progress)
+- Docker Compose for local PostgreSQL
+- Alembic migration `0001_initial_schema`
+- Seed script inserting 6 canonical topics
+- `.mcp.json` at repo root for Claude Code discovery
