+/**
+ * Service worker for Watched Folder retry scheduling.
+ *
+ * Reads the earliest pending retry from IndexedDB and sets a setTimeout for it.
+ * When the timer fires it posts PROCESS_DUE_RETRIES to all window clients so
+ * the main thread can atomically claim and process the due entries.
+ *
+ * Limitations:
+ *   - Browsers may terminate idle service workers after ~30 s. The main thread
+ *     therefore also drains due retries on mount and on visibilitychange as a
+ *     fallback — no retries are lost, they may just fire slightly late.
+ *   - Multiple clients each post a SCHEDULE_RETRY message; the SW deduplicates
+ *     by resetting the timer each time, so only one notification is sent.
