5f470993ff perf(handler): use RWMutex for FileInfoCache 
- Change FileInfoCache.mu from sync.Mutex to sync.RWMutex
- Get method uses RLock for concurrent read access
- Stats method uses RLock for read-only operation
- Double-check pattern for lock upgrades (TTL expiry, LRU move)

This improves concurrent read performance for the FileInfo cache,
which is read-heavy in static file serving scenarios.

8cc3fdef6f perf(handler): optimize static file serving performance 
- Add pathPrefixLen for zero-allocation path stripping
- Precompute ETag in FileCache.Set, reuse on cache hits
- Add MIME LRU cache with O(1) operations using container/list
- Remove sharded cache (eager LRU was slower than single-lock)
- Add FileInfo cache to reduce os.Stat calls (TTL-only strategy)
- Adjust test expectations for normalized root path format

Benchmark results: Lookup 12.7µs → 10.6µs (16% improvement)
