awsm-audio-player — the WebAudio playback engine for the awsm-audio editor.
[Player] owns the live AudioContext and a fixed master chain
(master gain → analyser → destination). [Player::play] instantiates an
authored [Graph] onto the context (see the build module) and routes it into the
master bus; [Player::stop] tears the instance down. The analyser exposes
time-domain samples for the editor's waveform view.
