-- 0006_ai_runs_status: ai_runs.status becomes the harness run outcome:
--   ok             the first reply was usable
--   repaired       the first reply was not, the repair turn's was
--   bad_output     neither reply was usable, or post-processing failed
--   provider_error the provider failed on either turn
-- A run's row is written once, when it ends, so there is no running state.
-- Nothing wrote ai_runs before the harness did, so no row holds the old
-- running or error values; if one does, the copy back fails the CHECK and
-- the migration stops rather than guess its outcome. created_at gains an
-- index for the 30-day purge. The rebuild is 0005's: copy the rows aside,
-- drop the table, create it again, copy the rows back and drop the copy.
--
-- suggestion_batches.ai_run_id and week_plans.ai_run_id reference ai_runs,
-- so foreign keys are deferred until commit, after the ai_runs rows are
-- back. The pragma lasts only for this migration's transaction.
