+/**
+ * Marks every existing `appstore.payload.*` / `appstore.payload_ts.*` row lazy.
+ *
+ * WHY. Until this release {@see AppStoreSource} wrote its payload cache as
+ * EAGER app config, and Nextcloud loads every eager row of every app on every
+ * request. One payload per managed app, ~4 MB for mail alone: measured on a
+ * dev instance 2026-10-06, 1,660 rows / 36 MB took ~300 ms of a ~450 ms
+ * `status.php`, slowing every page of the instance, not just this app's.
+ *
+ * The code now writes these keys lazy, and a write flips an existing row's
+ * flag. But a row is only rewritten when its app is listed again after the
+ * TTL, so a payload for an app nobody looks at would stay eager forever. This
+ * step flips them all at once.
+ *
+ * Idempotent: `updateLazy()` on a row that is already lazy changes nothing, so
+ * a fresh install and a second run both pass through without effect. Never
+ * raises: a cache row is not worth an aborted upgrade.
+ *
+ * @psalm-suppress UnusedClass Nextcloud instantiates repair steps from the
+ * `` block in appinfo/info.xml, which psalm does not read.
