Merged
Conversation
- Create KV-based sliding window rate limiter middleware - Apply rate limits to auth endpoints: - Login (JSON + form): 5 requests/minute - Register (JSON + form): 3 requests/minute - Password reset: 3 requests/15 minutes - Seed admin: 2 requests/minute - Includes Retry-After and X-RateLimit-* response headers - Graceful degradation: skips rate limiting if CACHE_KV not available - Export rateLimit from middleware/index.ts Fixes VULN-004
