-- Migration 006: summarization mode (per-user auto/manual + per-video queue).
--
-- auto_summarize is a per-user setting (not a global one): multi-user ready per
-- ADR-012. FALSE default makes MANUAL the out-of-the-box behavior — `tapir run`
-- discovers new videos but only summarizes the ones the user explicitly queued.
--
-- summarize_requested is the per-video manual queue flag. The web "Summarize"
-- button sets it TRUE; the next `tapir run` picks it up, summarizes, and clears
-- it back to FALSE. In auto mode it is unused.
--
-- No RLS policy changes needed: both columns are added to tables that already
-- carry user_id and have ENABLE + FORCE ROW LEVEL SECURITY (migration 003). A new
-- column on an RLS-protected table inherits that protection automatically — the
-- existing users_isolation / videos_isolation policies gate every row, so these
-- columns are only ever readable/writable for the row's own user.
