[FEATURE] codex integration

## Feature Description

I realize this will likely be marked as out of scope, but I figured I would try. Worst case, it'll stick around in closed issues as a warning to others.

I quite enjoyed this plugin up until I switched to codex recently. It would be nice to have it continue working, especially after I spent time setting things up.

Any effort here would be appreciated and I am happy to help test. Thank you!
