// this 'migration' is a bit different. it intentionally runs each time Libation is started. its job will be fulfilled when I eventually
// implement the portion which removes FilePaths.json, at which time this method will be a proper migration
//
// I'm iterating through safe steps toward getting rid of the live scanner except to track audiobook files as a convenience
// such as clicking the stop light to open its location. live scanning will be replaced with state tracking in the database.
// FilePaths.json => db. long running. fire and forget
