-- Audiobookshelf-style RSS podcast feeds. Each row exposes one
-- audiobook (library_item_id) as a public RSS XML feed reachable at
-- /feed/{slug}.xml — slug is the unguessable capability token.
-- closed_at is NULL while the feed is active; closing soft-deletes
-- so re-opening creates a new row with a new slug.
