RemoveMacAI Files

• Applying or undoing one tweak no longer resets a partly applied one, such as smart quotes off with dashes still on. A partly applied tweak only changes when you switch it yourself or name it in undo.
• App caches leaves alone the macOS caches whose names don't start with com.apple., such as CloudKit, FamilyCircle and GeoServices.
• Removing GarageBand keeps its sound library when Logic Pro or MainStage is installed.
• Unavailable simulators and Time Machine local snapshots now say they are deleted right away instead of moved to the Trash, and the button reads Remove when either is selected.
• Background Items marks each item as an updater or a helper, and warns before a helper such as a VPN or Docker is turned off.
• When one administrator step fails, the steps after it still run.
• An undo journal that can't be read is kept aside instead of being overwritten.
• The app only reports model space it measured.
• Command-line columns no longer run together, and off --dry-run lists only models that are on disk.
• The README says where to find Photos Clean Up.
