fix(labd): wire v2.0 Phase 1 routes into createApp + smoke tests

The v2.0 Phase 1 commit (04faa07) added AuthService, RbacService,
ResourceStore, AuditService, the bearer auth middleware, and the
v2-auth/environments/resources route files, but createApp() never
registered any of them. They sat in the codebase as dead code: a
running labd would 404 on /api/auth/login, /api/resources, /api/events,
etc.

Wiring (server.ts)
- Instantiate AuthService, RbacService, ResourceStore, AuditService at
  app creation. Cast DbClient to PrismaClient (the runtime db is a real
  PrismaClient; DbClient is a structural shim).
- Start AuditService timer, register an onClose hook to stop it on
  shutdown so we never lose the last batch.
- Register v2 routes inside a Fastify scope with the bearer-auth
  middleware as preHandler. v1 routes (registered on the root scope)
  are unaffected so existing labd clients keep working.

AuditService (audit.ts)
- Expose flushPending() so tests can deterministically observe events
  without leaning on the 5-second flush interval. Implementation
  delegates to the existing private flush().

Smoke tests (v2-smoke.test.ts, 11 cases)
- Bootstrap: first POST /api/auth/login with empty users creates the
  admin (role=ADMIN, hashed password), returns a 64-hex token, marks
  isBootstrap=true, emits an auth_bootstrap audit event. Second login
  uses the normal flow. Wrong password returns 401 and audits failure.
  Missing credentials returns 400.
- RBAC: missing/empty/invalid bearer tokens return 401. ADMIN role
  bypasses RBAC. A non-admin with no role bindings gets 403 with
  "no matching role binding". A user with an env-A binding is denied
  for env-B resources.
- Audit: bootstrap event is queryable via /api/events?correlation=...
  Explicit parent/child chain (shared correlationId, parentEventId)
  is preserved across emits.

All 246 workspace tests pass.

+## Skill routing
+
+When the user's request matches an available skill, ALWAYS invoke it using the Skill
+tool as your FIRST action. Do NOT answer directly, do NOT use other tools first.
+The skill has specialized workflows that produce better results than ad-hoc answers.
+
+Key routing rules:
+- Product ideas, "is this worth building", brainstorming → invoke gstack-office-hours
+- Bugs, errors, "why is this broken", 500 errors → invoke gstack-investigate
+- Ship, deploy, push, create PR → invoke gstack-ship
+- QA, test the site, find bugs → invoke gstack-qa
+- Code review, check my diff → invoke gstack-review
+- Update docs after shipping → invoke gstack-document-release
+- Weekly retro → invoke gstack-retro
+- Design system, brand → invoke gstack-design-consultation
+- Visual audit, design polish → invoke gstack-design-review
+- Architecture review → invoke gstack-plan-eng-review
+- Save progress, checkpoint, resume → invoke gstack-checkpoint
+- Code quality, health check → invoke gstack-health

+# TODOS
+
+## P1 — Ship with Phase 1
+
+### v2.0 Architecture Document Update
+Update `bastion/docs/ARCHITECTURE.md` to cover v2.0: driver model, fleet system,
+Pulumi integration, Vault secrets, Deno evaluator, new CLI grammar. The existing
+doc covers v1.0 comprehensively (432 lines). v2.0 adds 5+ major subsystems.
+**Effort:** M (human: 1 week / CC: 1-2 days)
+**Depends on:** Phase 1 complete
+**Source:** CEO review 2026-04-01
+
+## P2 — Post-v2.0 Core
+
+### SSH Emergency Mode (scoped)
+SSH-based operations limited to: (1) earliest necessary box provisioning before agent
+is installed, and (2) emergency debugging/fixing operations that can't be done via agent.
+NOT a general-purpose DeploymentTarget alternative. The v1.0 `recheck` and `fix-ssh-root.sh`
+patterns are the model. Agent stays the primary management path.
+**Effort:** S (human: 1 week / CC: 1 day)
+**Depends on:** Phase 2 complete (DeploymentTarget interface exists)
+**Source:** CEO review 2026-04-01
+
+### Prometheus Metrics Endpoint
+Add `/metrics` endpoint to labd: resource counts by status, apply duration histograms,
+driver operation latency, fleet pipeline completion rates. Standard Prometheus scraping
+for Grafana dashboards and alerting.
+**Effort:** S (human: 2-3 days / CC: 2-3 hours)
+**Depends on:** Phase 1 (labd exists with resource store)
+**Source:** CEO review 2026-04-01 (observability gap)
+
+## P3 — Future Enhancements
+
+### Infrastructure Graph Visualization
+Visual representation of resource dependencies, environment topology, fleet status.
+Could be a web UI or terminal-based (like `kubectl tree`).
+**Source:** CEO review 2026-04-01
+
+### `labctl import` for Existing Cloud Resources
+Discover and import existing AWS/GCP resources into the state store.
+Pulumi's import functionality could be leveraged.
+**Source:** CEO review 2026-04-01
+
+### Built-in Secrets Rotation
+Automatic rotation of managed secrets (database passwords, API keys).
+Vault handles rotation but a labctl-native workflow could simplify.
+**Source:** CEO review 2026-04-01
