First of six sub-plans for the absorption. Six tasks: a discovery
audit that resolves the spec's Risk questions, four idempotent SQL
migrations (abs_sessions, podcast_feeds, media_libraries.kind,
audiobooks.enabled feature flag), and an empty-but-compiling
internal/audiobooks package scaffolded into cmd/silo. Lands as a
strict no-op for users (feature flag defaults to false).

Plan to absorb silo-plugin-audiobooks into silo-server as a first-party
feature. Audiobooks land in silo's existing SPA; ABS clients connect
directly. Hard constraints: reuse existing tables (media_items,
media_files, user_watch_progress, user_playback_sessions, people,
item_people, library_collections); only two new tables (abs_sessions,
podcast_feeds) and at most one column add (media_libraries.kind);
silo's main :8080 listener handles ABS Socket.io natively. Out of
scope: audiobook requests flow, smart collections, share links,
external recommender, custom metadata providers, separate audiobook
SPA.
