The repo never enforced rustfmt, so formatting had drifted broadly. This is a
single mechanical `cargo fmt` pass over the whole crate (no behavioral change;
lib suite green, 493 passed). Going forward fmt should be enforced (planned CI
fmt --check step). Part of the 0.6.1 hygiene pass.

Ten more cases pinning the SoftLimiter contract (Gemini, senior-audited):
sustained-loud ceiling both polarities, out_gain participation (boost + atten),
instant-attack no-overshoot, release direction/monotonicity + gradualness,
cross-call state continuity (split == continuous), empty input, extreme
i32::MIN/MAX magnitudes, and bit-exact transparency just under the ceiling.

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.
