Ducker

Sidechain ducker. Inserts on the *target* bus (e.g. music) and listens to the level of a source bus (e.g. voice). When the source is loud, the target's gain drops; when quiet, it returns. Implementation: an envelope follower running on the source bus's RMS, driving an additional gain node spliced into the target's FX chain. The envelope follower runs on the main thread at ~60 Hz — fine for a speech ducker, not for sample-accurate audio-rate sidechaining. For that, use a custom AudioWorklet (planned).
