Pyrefly locks Neovim after type checking is complete.

[stephenprater]

Describe the Bug

1. Use Pyrefly in Neovim via any method.
2. In another terminal open top or equivalent
3. Verify that Neovim has started a Pyrefly subprocess.
4. The type check will run and you should see a spike in CPU usage for pyrefly.
5. Navigate around the code base to a file with an error - within a few seconds the UI will freeze for a few seconds.
6. Sometimes the UI will hang unrecoverable.

You can do LspRestart pyrefly repeatedly until you hit problem 6.

This seems specific to the Pyrefly LSP. "Basedpyright" reports more extensive errors, but does not lock the UI.
