AudioGraphBuilder.compressor() method

A feed-forward dynamic range compressor (linked channels — one gain across all channels, so the image doesn’t shift; log-domain soft knee; branching attack/release smoothing; makeup gain). All parameters are runtime-tunable via AudioGraphNode.setParams(); makeupDb honours a transition. Defaults: −20 dBFS threshold, 3:1, 6 dB knee, 5 ms attack, 50 ms release.
