 /*
  * FileCache — Enhanced File Cache for libhv HTTP server
  *
- * Features:
- *   1. Configurable max_header_length (default 4096, tunable per-instance)
- *   2. prepend_header() returns bool to report success/failure
- *   3. Exposes header/buffer metrics via accessors
- *   4. Fixes stat() name collision in is_modified()
- *   5. max_cache_num / max_file_size configurable at runtime
- *   6. Reserved header space can be tuned per-instance
- *   7. Source-level API compatible; struct layout differs from original (no ABI/layout compatibility)
