IllegalStateException: InventoryCloseEvent may only be triggered synchronously (ResidenceChangedEvent / async task)

[qwejerrywolf-AU]

Describe the bug
When a player crosses a Residence boundary, an exception is thrown indicating that InventoryCloseEvent is being triggered asynchronously.

Paper/Purpur strictly enforces that InventoryCloseEvent (and HumanEntity#closeInventory()) must only be called from the main server thread, but Residence currently calls it from an async task, causing the event to be rejected.

This does not crash the server, but it breaks Residence logic (fly/special flag handling) and continuously spams ERROR logs.

To Reproduce
1.Start a Paper / Purpur server (1.21.11)

2.Install the following plugins:

Residence 6.0.1.2

CMILib 1.5.8.2

3.Create at least two adjacent Residence regions with different flags
(for example, regions that affect flying or other special player states)

4.Have a player open any inventory GUI
(e.g. chest, ender chest, or plugin GUI)

5.While the inventory is still open, move across the Residence boundary

6.Observe the server console

This issue also occurs in paper 1.21.11

This event should be executed on the main thread and not through an asynchronous thread
