Changes

perf: implement Handle Reuse and Privilege Caching optimization

• Make enable_backup_privileges() public for thread-level caching - Add get_wof_algorithm_from_handle() to separate handle creation from logic - Add smart_compress() that opens file once and reuses handle for detection + compression - Call enable_backup_privileges() once per consumer thread instead of per-file - Update try_compress_with_lock_handling to use smart_compress Reduces syscalls from 2+ per file to 1, and privilege adjustments from per-file to per-thread.
