Route login, text, and protocol-request packets through a single
_consume_via_local_candidates fan-out that offers each one to every local
candidate sharing the one-byte destination hash — the companion bridge and the
room-server/repeater identity — and consumes it only when one MAC-verifies it.
A prefix collision with a remote node (or a forged packet) is left for the
forwarding engine instead of being swallowed.
- gate processed_by_injection on the core HandlerResult.authenticated
- protocol-request now forwards on collision instead of always marking handled
- add real-crypto integration tests (text, room-server login, protocol-request)
and router fan-out tests covering companion + room-server collisions
