+/**
+ * Patch: fix Bluesky notification polling cursor misuse.
+ *
+ * The Bluesky `listNotifications` API cursor is a PAGINATION cursor —
+ * it moves BACKWARDS in time (older pages). Using it as a "poll since
+ * last check" marker causes each poll to fetch progressively older
+ * notifications. Over time the cursor drifts far into the past, beyond
+ * Bluesky's notification history window, so every poll returns an empty
+ * list and no new interactions are ever stored.
+ *
+ * Fix: remove the cursor from the fetchBlueskyNotifications call so it
+ * always fetches the latest notifications (most-recent page), and rely
+ * on platform_id deduplication (upsertConversationItem) to avoid storing
+ * duplicates. Also clear any stale bluesky_cursor from the DB state so
+ * the dashboard no longer shows a misleading 2024 timestamp.
