- ResponseCache: Redis-backed HTTP response caching for public GET endpoints
with configurable TTLs per endpoint prefix (tracks 15m, search 5m, etc.)
- CacheHeaders: CDN-optimized Cache-Control headers per asset type
(static 1yr immutable, audio 7d, HLS 60s, images 30d, API no-cache)
- Integrated both middlewares into the router middleware stack
- Unit tests for cache key generation, header rules, and config
