+/**
+ * Patch: filter out self-interactions from own Bluesky account.
+ *
+ * When posts are syndicated to Bluesky, the resulting Bluesky post can
+ * generate notifications (likes, reposts, mentions) attributed to the
+ * site owner's own account. These self-interactions should not appear
+ * as inbound interactions.
+ *
+ * Two-pronged fix:
+ *  1. scheduler.js  – skip storing new notifications where the author
+ *                     handle matches BLUESKY_IDENTIFIER / BLUESKY_HANDLE.
+ *  2. conversations.js – strip self-authored items from API responses so
+ *                        any already-stored entries are hidden immediately.
