Replace the mixer's per-sample hard clamp with a lossless i32 bus sum fed through a feed-forward soft limiter (instant attack, ~120ms release). Below the ceiling it's transparent and sample-exact; loud multi-peer moments are ridden down to the ceiling instead of shattering into hard-clip distortion. State carries across frames so a sustained-loud stretch doesn't re-attack every 20ms frame. The master output gain now applies inside the limiter so a boost past the ceiling is limited too. mix_frames now returns the lossless i32 sum (saturation responsibility moved to the limiter); its tests assert losslessness, and the new limiter module carries the saturation/transparency/release guarantees.
