Cmux Ghostty

This handles the Ghostty terminal submodule workflow for the cmux project, including rebuilding the GhosttyKit.xcframework with proper Release optimizations, managing the fork relationship with upstream, and updating submodule pointers safely. You'd use this when modifying Ghostty itself, syncing with upstream changes, or documenting fork conflicts. The skill emphasizes submodule safety rules like never committing on detached HEAD and always pushing submodule commits before updating the parent pointer. It's focused on a specific project setup, so only useful if you're working on cmux or have a similar forked submodule workflow where you need to maintain changes against an upstream while building platform specific frameworks.
