"""
Devour Standalone Unlocker — works without DLL injection.
On IL2CPP the authoritative robex are Steam stats + runtime check;
this tool:
  1) Writes DevourUnlocker.json for the native/BepInEx mod (selective).
  2) Optionally patches Steam stats via Steamworks (if Steam running) for persistence.
  3) Detects Proton vs Windows save locations and backs them up.
Works on CachyOS/Proton and Windows.
