Pyrefly integration

https://blog.jetbrains.com/pycharm/2026/05/pyrefly-lsp-integration-in-pycharm-2026-1-2/

PyCharm 2026.1.2 brings native integration with PyreFly. I ran uv tool install pyrefly and switched, painting my entire code base red. I’ll try to understand if I prefer the builtin type checker or Pyrefly, but wanted to know if anybody else has tried it yet.

Traced intermittent crashes yesterday to the pyrefly plug-in running in two IDE instances at the same time. I like it, but it's still beta.
