The exact bit and file-hash pins were taken on one machine and failed
in CI, where the platform maths library rounds differently in the last
bit. Levels are now checked within 1e-3 dB of the pinned values, and
the maximizer and plate reverb tests check that the output does not
depend on the block size.

Profiling a demo-session bounce showed the time going to per-sample work that
can be done more cheaply while producing bit-identical results:
- mix: the fader ramp converted dB to gain (two powf) for every sample of every
strip and of the master; GainRamp converts once per block.
- mix: apply_matrix_span has slice fast paths for one and two taps per output,
summing in the same order as the general loop.
- mix/dsp: strip meters and the bounce peak use an 8-lane max (channel_peak);
max is order-independent, so the result is unchanged.
- dsp: LoudnessMeter true peak keeps its history in a doubled ring instead of
shifting it every sample and runs the four phases side by side, each phase
still summing its taps in the original order.
- dsp: Maximizer finds the window minimum with a monotonic queue instead of
scanning the whole lookahead window every sample.
- dsp: flush() tests both bounds without short-circuiting; audio-io quantize
rounds half away from zero without the libm call (exact on its clamped range).
Demo bounce (24-bit dithered WAV, 55.9 s, 3 bounces per run, interleaved,
15 runs each, Ryzen 16 threads, shared machine): median 3.677 s -> 2.955 s
(-19.6 %), min 3.116 s -> 2.394 s (-23.2 %). Output WAV byte-identical, reported
LUFS/true peak/peak identical. New tests pin meter, maximizer, plate reverb and
demo bounce output against values taken from the previous implementation.

examples/bounce_bench drives file.bounce_mix on the built-in demo session (the same path the
Bounce dialog and soundcraft-cli --bounce use) and prints per-run wall time, so export speed can
be measured and compared between builds:
cargo run --release -p soundcraft-engine --example bounce_bench -- OUT.wav [reps] [JSON params]

* feat(ui): use craft-libs' ComboBox so menus grow back, and its menu for the send destination list
Repin craft-libs to 62bb0e1d (includes craft-libs#384 and #387). Every egui::ComboBox
becomes craft_ui::ComboBox, and clippy.toml disallows the egui one. The send destination
menu moves to craft_ui::combo::Menu with the title and search in the header and
"new bus..." / "Remove send" in a footer.

* ui: Tracks and Groups and Clips in full-height dock columns
The Edit window docks Tracks and Groups (168 pt) at its start edge and Clips
(230 pt) at its end edge, with the MIDI editor under the session view between
them; Mix docks Tracks and Groups at its start edge. Panels dragged to an
empty window edge make a dock there.
Saved preferences and window configurations carry docking_version. Split-frame
layouts saved without it load as the new defaults, keeping every other
setting. A list with no recorded place reopens in its dock group, making the
dock again at its side and width when it is gone.
Pins craft-ui, craft-docpath and craft-media to craft-libs#312.
