Add SyncWorker for Room serialization

[SirrWilliam]

2. Cannot Capture Prisoners
   (Breaks a core game mechanic)
   Observed Result: Attempting to capture a downed enemy pawn fails, even with available prisoner beds. The action throws a SerializationException in the UI.

Exception filling window for Verse.FloatMenuMap: Multiplayer.Client.SerializationException: No writer for type Verse.Room

Analysis: The multiplayer mod is missing a serializer for Verse.Room. This prevents the game from correctly syncing the capture action, which requires room data to validate prisoner beds.
