Patch and extend the installed macOS Codex desktop app by editing `/Applications/Codex.app`, including header buttons, side panels, message rendering, Electron bundle behavior, `app.asar` patching, `ElectronAsarIntegrity` updates, ad hoc re-signing, rollback backups, and relaunch/resume checkpoints. Use when Codex needs to inspect, modify, repair, re-sign, relaunch, or resume work on the installed app on macOS, especially after prompts that explicitly mention `$cannibal`, Codex modifying itself, top-right toolbar changes, side panels, chat UI changes, installed app patches, or restarting Codex without losing progress.
