Added

• Configurable debug-mode option in config.yml with three levels:
  • 0 (Disabled) – no debug output
  • 1 (Simple) – only important messages (startup, auto-invites, reloads)
  • 2 (Verbose) – all messages including per-player item updates (may spam console)
• All debug log messages are now written in English.

Fixed

• Configuration file comments are now preserved across server restarts and plugin reloads. The plugin no longer overwrites user comments with saveConfig().
