"#;Expand description
Migration to record whether a cached item is a folder/container vs a playable
leaf. Needed so channel items (which can be either) route to the player or to
a browse list correctly. Existing cached rows predate the column and have an
unknown folder flag, so we force a refresh by clearing their synced_at,
causing the hybrid repository to re-fetch them from the server on next browse.
