fix: bounce silent — AudioRoutingEngine no longer full-tears-down sink on dest change

Browse Source 
stopAllPlayback->updateSfRouting->startTrackPlayback reroutes bridge sink
twice during bounce; each dest change previously called this.disconnect()
= BridgeAudioNode teardown + async worklet reload, audio swallowed into
_preBuffer (bounded 64 blocks) forever if worklet never reactivates ->
silent WAV (only old reverb tail). Fix: rely on BridgeAudioNode.connect()
re-pointing _gainNode (already handles dest switch without teardown);
init() only when not ready. Add __sfDiag ROUTE + BRIDGE_AUDIO (frames/
peak/path per sec) to verify at bounce end.
