/**
* MetaMesh Plugin: torrent
*
* ============================================================================
* PLUGIN MOUNT ARCHITECTURE - DO NOT MODIFY WITHOUT AUTHORIZATION
* ============================================================================
*
* Each plugin container has exactly 3 mounts (2 for plugins without output):
*
* 1. /files (READ-ONLY) - Shared media files, read access only
* 2. /cache (READ-WRITE) - Plugin-specific cache folder
* 3. /files/plugin/<id> (READ-WRITE) - Plugin output folder (if needed)
*
* This plugin (torrent) only requires mounts 1 and 2:
* - /files (RO) - to read .torrent files
* - /cache (RW) - to cache parsed torrent metadata
*
* SECURITY: Plugins must NEVER write to /files directly.
* All write operations go to /cache or /files/plugin/<id> only.
*
* ============================================================================
