1128eb644f perf(static): enable FileInfoCache by default with negative caching 
Production static file serving now uses FileInfoCache by default
with a 2-second TTL in router.go, dramatically reducing os.Stat
syscalls for missing files and repeated paths.

Changes:
- Add negative cache support to FileInfoCache (caches 'not found' results)
- Introduce statWithCache() helper in StaticHandler for uniform caching
- Make FileInfoCache TTL configurable via SetTTL()
- Default cacheTTL=0 disables caching in NewStaticHandler (tests compat)
- router.go enables fileInfoCache with 2s TTL for all static handlers

Benchmark (repeated 404s):
  No cache:    ~2651 ns/op, 2225 B/op, 15 allocs/op
  With cache:  ~1505 ns/op, 1905 B/op, 12 allocs/op
  Improvement: -43% latency, -14% allocations

This addresses the dominant allocation source in v0.4.0 profile
(os.statNolog at 74.95% of allocations).

b62a3f12da feat(handler): add autoindex module for directory listing 
Add nginx-like autoindex functionality with three output formats:
- HTML: styled directory listing with sortable columns
- JSON: structured API-friendly output
- XML: machine-readable format

Configuration options:
- auto_index: enable/disable directory listing
- auto_index_format: output format (html/json/xml)
- auto_index_localtime: use local time instead of GMT
- auto_index_exact_size: show exact bytes vs human-readable

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)
