Subject: [PATCH] fix(x): FakeTurnEventBus satisfies ITurnEventBus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The interface grew subscribe/subscribeAll when the IPC bridge moved
to resolving ITurnEventBus, but the runtime-test fake still only had
publish — a TS2739 invisible to vitest and the build tsconfig. The
fake now declares 'implements ITurnEventBus' so the next interface
change fails loudly here instead of silently drifting.
