Further unfrig playwright (#5794)

* Bail on cleanup after 10s; move setup even higher

* Give macos time before starting an electron instance

* Try it again

* Again

* Remove stale TODO

* Use Kolmogorov complexity instead of text for ai assertions

* Help out prompt-to-edit test with being more explicit

* Try to give Mac more time to open a window

* Fix the other var change for prompt-to-edit test

* Forgot this

* Try some crazier shit

* 🤦 I forgot the return.

* Ok things were actually just not working well at all

* Fix export test to expect smaller size

* yarn tsc && yarn lint && yarn fmt
