When a Carpet mod Fake_player logs off (disconnects from the server), its marker/entity does not disappear from the BlueMap. The player's position remains visible on the map and causes high CPU usage unless the server or BlueMap is restarted.

Steps to Reproduce

1. Spawn a player using the Carpet mod (e.g., via  /player xxx spawn).
2. Confirm the player is visible on BlueMap at its current in-game position.
3. Make the player log off (e.g., via  /player xxx kill  command or relevant Carpet mod functionality).
4. Check BlueMap again— the player’s marker/entity is still present and does not reflect its offline state.

Expected Behavior

The Carpet dummy’s marker/entity should automatically disappear from BlueMap immediately after it logs off, consistent with how player markers behave when disconnecting.

Actual Behavior

The dummy’s marker/entity persists on BlueMap even after it has logged off, leading to inaccurate map representation.

Environment

• BlueMap Version: 1.21.8-5.11-fabric
• Carpet Mod Version: 1.21.7
