Module file_storage 

File-system-based storage backend for certon.

This module implements Storage using the local file system. Highlights:

• Atomic writes — data is first written to a temporary file in the same directory, then renamed into place so that readers never see a partial write.
• Distributed locking — lock files containing a JSON timestamp are created atomically. A background keepalive task periodically updates the timestamp; stale locks whose timestamp exceeds twice the freshness interval are automatically removed.
• Platform-aware defaults — the default storage path follows OS conventions (~/.local/share/certon on Linux, ~/Library/Application Support/certon on macOS, %APPDATA%/certon on Windows).
