Table was referenced in migration 0005's comment but never created —
this slice fills the gap. Soft-delete via deleted_at column; hot-path
partial index on active rows; GIN index on session_vector for
M3 sub-plan #3's similarity queries.
Three tables keyed on (user_id, entity_id) with liked_at. Per-table
indexes on (user_id, liked_at DESC) for the recently-liked feed.
sqlc queries cover like/unlike/list-rows/count/list-ids per entity.
Tables and indexes per spec §5. session_vector_at_play ships nullable
so M3 doesn't need a follow-up migration. Table is named play_sessions
to avoid collision with the existing sessions (HTTP auth) table from
migration 0004.
Stores sha256(token) plus user_agent + last_seen_at so future
active-sessions UI doesn't need another migration.

Subsonic token auth (t=md5(password+salt)) needs a reversibly stored
credential; bcrypt password_hash can't serve. NULL means the user has
not opted in, forcing apiKey (OpenSubsonic) instead.
