backend-ci.yml's `test -z "$(gofmt -l .)"` strict gate (added in
c96edd692) failed on a backlog of unformatted files. None of the
85 files in this commit had been edited since the gate was added
because no push touched veza-backend-api/** in between, so the
gate never fired until today's CI fixes triggered it.
The diff is exclusively whitespace alignment in struct literals
and trailing-space comments. `go build ./...` and the full test
suite (with VEZA_SKIP_INTEGRATION=1 -short) pass identically.
- 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
