* TST-012: Security Test Suite (CC-046)
*
* HTTP-level security tests via NestJS TestingModule + supertest.
* Covers: SEC-003 (authentication), SEC-004 (tenant isolation guards),
* helmet headers, CORS enforcement, route enumeration safety,
* CASL agent tool registry policy.
* Self-contained: uses a minimal stub guard to simulate real auth behavior
* without importing SessionGuard (which pulls in drizzle/pg at module level).
*
* DB and Supabase are mocked no real connections needed.
* JWT verification uses the real jose/GoTrue path but without a valid
* SUPABASE_JWT_SECRET, so any bearer token throws UnauthorizedException.
* Tests cover:
* - SEC-003: Authentication enforcement (401 on missing/invalid token)
* - Helmet security headers
* - CORS origin whitelist enforcement
* - Route enumeration safety (404 not 500, no stack leaks)
* - CASL agent tool registry policy (unit, no HTTP)
