- Nuclear option: completely wipe Application Support on each launch

bogdan committed a month ago
Remove the entire Application Support directory and recreate it fresh on every app launch. This completely eliminates any possibility of schema corruption from previous database state. This is safe because SwiftData will create fresh stores with the correct schema on first access. All user data is lost, but this is a development build anyway.
