fix(scan): force-kill stale AE processes before each launch (fresh start)
PrepareFreshAE = taskkill AfterFX/aerender/AfterFXLib/dynamiclinkmanager/QT32
+ 2s settle + clear crash markers, then launch. A hung/zombie AE from a prior
job would otherwise block or corrupt the new run. RunScan now calls it.
