xfy bd9e87128d perf(ssr): optimize request throughput by 32%
- Cache ammonia::Builder with LazyLock (was rebuilt per request)
- Enable tracing release_max_level_info to strip tracing overhead at compile time
- Remove TraceLayer and tower-http trace feature from production
- Increase DB pool size 10→20 (configurable via DB_POOL_SIZE)
- Increase SSR cache TTL 300s→3600s (configurable via SSR_CACHE_SECS)

Benchmark: 7,444 → 9,840 req/s, P99 latency 27.6ms → 11.1ms
