+//! Background Forgejo notification poller.

+//! Reads `HIVE_FORGE_URL` + `{HYPERHIVE_STATE_DIR}/forge-token`, polls
+//! `GET /notifications?all=false` every 30 seconds, and delivers each
+//! unread notification as a broker `Wake { from: "forge" }` message so
+//! claude's normal turn loop picks it up.
+//!
+//! Graceful no-ops:
+//! - `HIVE_FORGE_URL` not set → disabled (no forge configured)
+//! - token file absent → disabled (agent has no forge account yet)
+//! - HTTP errors → logged at debug, retry next tick
+//!
+//! After successfully delivering a notification it is marked read via
+//! `PATCH /notifications/threads/{id}` so it does not re-fire. If delivery
+//! fails the thread is left unread so it resurfaces next tick.
