+`draft/webpush` adds encrypted **Web Push** (RFC 8291 payload encryption + RFC 8292
+VAPID) so a PM or highlight reaches a client whose tab is backgrounded or closed. The
+client subscribes with `WEBPUSH REGISTER <endpoint> p256dh=<b64url>;auth=<b64url>` (and
+`WEBPUSH UNREGISTER <endpoint>`); the server encrypts a small JSON copy and POSTs it to
+that push endpoint — off the core thread — with a VAPID `Authorization` header, while
+the subscriber is away. The server's VAPID public key is advertised via ISUPPORT
+`VAPID=`. Its keypair is auto-generated and persisted on first start; behaviour is
+tuned by `webpush` / `webpush_away_only` / `webpush_ttl` / `webpush_sub`.
