-- 1.29.2 — concurrency data-corruption fix (deferred-flush lost-update +
-- VACUUM stale-snapshot + read_rotation/read_ids_only stale-meta races).
-- Code-only fix: no wire-format change (stays v7), no SQL surface change,
-- no REINDEX to upgrade. Existing indexes are read + written correctly in
-- place by the new .so. This migration is intentionally empty (no SQL
-- objects added/changed); the fix lives entirely in the extension binary.
