If the .config directory (or its children, like lib) was deleted, ConfigFile would crash because it would try to open or create a file in a directory that didn't exist. Therefore, for user and library configs (but not system configs), ensure that the parent directories exist. This allows the user to delete the entire .config folder and all apps still work. (Except those which can't handle missing config. That's a separate issue though.) Fixes #13555 Note: Some changes to pledges and unveils are necessary for this to work. The only one who can recreate .config at the moment is ConfigServer, as others probably don't pledge the user home directory.
