/**
 * Migration 089: Add `job_cancellations` audit table for issue #901.
 *
 * Operators cancel `memory_jobs` and `summary_jobs` rows via the
 * `cancelObsoleteJobs` repair action. We never hard-delete the source
 * row in cancel — we copy the full payload to `job_cancellations` and
 * flip the source row's `status` to `cancelled`. This preserves
 * provenance for support cases where operators need to explain a
 * cancellation after the fact.
 *
 * Idempotent: `CREATE TABLE IF NOT EXISTS` + index check via
 * `pragma_index_list`. Safe to re-run on a partial upgrade.
