Research direction
Read the shutdown() entry point and the UIState ownership and lifetime paths described in the report. Determine how a shutdown hook could let the detached server stop before shared state is destroyed, then verify that closing the main window completes without the reported shared_ptr error.

Description
Hi, I encountered an issue that seems need some customization to the shutdown() function:
I have a separate thread initiated and detached before polyscope::init() -- a server listening from other software for sending geometries in.
The server use a shared_ptr<UIState> which is also used in the main().
Now if I close the main window of polyscope, there's always an error pointing to the ~shared_ptr<UIState>.
I'm not 100% sure what happened there, but it seems the main thread delete the shared_ptr<UIState> before the other thread exit. And when the server tries to delete that shared_ptr, it points to nowhere?
I assume manually exit the separate thread before the main should help.
