fix(scan): also clear AE AppStates registry to stop Safe Mode 'Crash Repair' dialog

SCRPriorState.json alone didn't suppress it — AE's per-session GUID under
HKCU\Software\Adobe\After Effects\AppStates persists after a kill/crash and
trips Safe Mode. ClearAECrashState now reg-deletes AppStates too (reg.exe, no dep).
