v0.23.1

Fix SCATTER double-tracking each peer: connection_added appended to
@connections and then called add_round_robin_send_connection, which
appends again. connection_removed deleted only one entry on disconnect,
leaving a stale one behind.

+- **SCATTER double-tracked each peer.** `Routing::Scatter#connection_added`
+  appended to `@connections` and then called `add_round_robin_send_connection`,
+  which appends again — so every connected peer had two entries in the list.
+  `#connection_removed` deleted only one on disconnect, leaving a stale entry
+  behind. Fixed by dropping the duplicate append.
