Meta ships Muse Code only as a binary, so it installs from the AUR (muse-code-bin) instead of mise, and a fresh install runs the muse login browser flow in the install terminal before the agent opens.

Adds Meta's Muse Code to Setup > Defaults > Agent. Selecting it installs Meta's official launcher through mise's HTTP backend and opens the agent through the shared default-agent flow. Mise discovers versions from Meta's stable channel; the launcher downloads, verifies, and updates the native binary for the current platform.
Muse ships with a lazy mise stub, so the download happens on first use. Setup and a migration for existing installs preserve user-managed launchers; the migration also respects the preinstall opt-out. Remove Preinstalls removes only the Omarchy wrapper. No usage collector is added.
