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).
- proxyDebugLog: move Enabled() guard to call sites to avoid allocations
- proxyDebugLog: add default case for unsupported types
- static routes: remove unintended regex support to match original behavior
Add typed ConflictError for path conflicts, change register functions
to return errors, handle conflicts as warnings and fatal errors as
startup failures. Remove all 20 instances of ignored Add* return values.
Add registerLuaRoutes method for router-based route registration
and call it in startMultiServerMode to fix Lua routes not working
when multiple servers are configured.

Add two new functions to router.go:
- registerLuaRoutesWithLocationEngine: registers Lua scripts with Route
config to LocationEngine with support for exact/prefix/regex matching
- wrapRoutedHandler: wraps route handlers with basic middleware chain
(accesslog + errorintercept)

Extract duplicate static handler configuration logic from
registerStaticHandlersWithLocationEngine and registerStaticHandlers
into a new configureStaticHandler method.
- Create configureStaticHandler() to handle alias, cache, gzip,
symlink, internal, expires, and autoIndex configuration
- Both registration functions now call the shared configuration method
- Registration logic remains separate (LocationEngine vs Router)

The registerStaticHandlers function (used in multi-server mode) was missing
AutoIndex and Internal configuration that registerStaticHandlersWithLocationEngine
already had. This caused auto_index to not work in multi-server mode.

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
