ced4568andClaude Sonnet 5 c8dd33522f feat(provisioner): add disposable lab lifecycle
Internal-only service (platform/provisioner/) implementing the environment
lifecycle from docs/PHASE1_PLATFORM_FOUNDATION.md: provision -> running ->
(reset -> running | destroy -> destroyed), plus experimental suspend/resume
(decision #3 — never on the guaranteed path, never relied on for correctness).

- src/docker.js — the lab-host abstraction (correction D). Resolves a
  lab_hosts row into a connected dockerode client, unix:// socket or tcp://
  with TLS client-cert auth. Refuses to connect to a tcp:// endpoint with no
  TLS material configured rather than connecting unauthenticated. Validated
  against both a local socket and a real remote Docker-in-Docker TLS endpoint
  during testing — same code path either way, only the lab_hosts config
  differs, which is the entire point.

- src/lifecycle.js — provision/destroy/reset/suspend/resume orchestration,
  wired to docker.js + egress.js + the Postgres registry. Every Lab container
  is privileged (required for k3s, not avoidable), gets its own Docker network,
  no published host ports, deterministic naming (rootnode-lab-<short-id> /
  rootnode-lab-net-<short-id>), and a CSPRNG routing token. Includes
  reconcileOnStartup(), implementing the "don't trust stale state after a
  crash/restart" requirement from docs/LAB_ARCHITECTURE.md §8 — verified by
  killing a container out-of-band and confirming a Provisioner restart flags
  the mismatch instead of trusting the stale 'running' row.

  Found and fixed during testing: a provisioning failure (e.g. readiness
  timeout) left an orphaned container/network/firewall chain behind with only
  the DB row marked 'error'. provisionEnvironment's catch block now does
  best-effort teardown of whatever was already created before marking the row
  error — confirmed by deliberately failing a provision and checking no
  container/network/chain survived it.

- src/server.js — the internal HTTP API (X-Provisioner-Key shared-secret auth
  on every route, matching the instructor-passcode pattern already used for
  the roster endpoint). Input validation on student_id/environment_id,
  structured JSON errors with a request id, routing tokens redacted from every
  response.

- docker-compose.dev.yml — Postgres + egress-proxy + provisioner on one
  machine (the documented Phase 1 dev exception). provisioner and egress-proxy
  run with network_mode: host + NET_ADMIN/NET_RAW, which is what lets
  src/egress.js manipulate the host's DOCKER-USER chain without needing
  interactive host sudo.

# iptables is required at runtime for egress.js — the Provisioner manipulates the host's

# container to run with --network host --cap-add=NET_ADMIN --cap-add=NET_RAW (see
# docker-compose.dev.yml). This is not a "nice to have" — without those run flags the
# Provisioner cannot enforce egress at all, only fail loudly, which it does.
