cmux Ghostty

GhosttyKit builds

Always rebuild the xcframework with Release optimizations:

cd ghostty && zig build -Demit-xcframework=true -Dxcframework-target=universal -Doptimize=ReleaseFast

Submodule workflow

Ghostty changes are committed in the ghostty submodule and pushed to the manaflow-ai/ghostty fork. Keep docs/ghostty-fork.md current with fork changes and conflict notes.

Always run git remote -v first and push to whichever remote is manaflow-ai/ghostty. .gitmodules sets the submodule URL to that fork, so in a normal checkout it is origin; older setups tracked upstream as origin and added the fork as manaflow. Substitute the right name below.
