Converting clip gain to volume (and baking volume into clip gain)
evaluated the clip's gain envelope by walking it from the start for
every breakpoint being converted, so a large envelope in an opened or
imported session cost envelope points squared and blocked the engine.
Build a running-maximum index over the envelope once per clip and
binary-search it. It returns exactly what the walk returned, including
for envelopes stored out of order.
Bundle entries are stored, so the files read out of one can only
outgrow the bundle when several entries point at the same bytes. A
small bundle naming one payload thousands of times was copied out once
per name, up to the 1 GiB total limit, in the browser. Check the
archive for overlapping entry data before reading any entry.
Its help said `<plugin id>`, but it only runs built-in plugins, and a
hosted id (clap:, vst3:, au:) failed as "unknown process". The help now
says built-in plugin id, and a hosted id gets an error saying AudioSuite
runs built-in plugins only.
Fixes#1301.
Bounces passed no bwf to the encoder, so mix and stem WAVs had no bext
chunk and post tools placed them at zero. Bounce::new now stamps them
with TimeReference = the session's timecode start plus the bounce start,
in samples since midnight, as other DAWs do. A caller's own bwf wins;
AIFF and FLAC have no bext and are unchanged.
Fixes#1296.

With start now optional, {end} alone resolves the start from the
selection; the empty-range fallback still went through event.tempo,
which put the tempo at tick 0. CodeRabbit flagged this.

Collapse consecutive duplicate SMF tempos only if the session tempo at
the event tick already matches, so existing session tempo markers are
overridden as expected.
import_midi_bytes capped meter changes at MAX_MIDI_METERS (10,000), but
left imported tempo events and synth tracks unbounded. Dense MIDI files
inserted unlimited tempo markers into the session tempo map, degrading
linear tick-to-sample conversions across playback and audio processing,
and instantiated up to 4,096 synth tracks for controller-only tracks.
Add MAX_MIDI_TEMPOS (10,000) and MAX_MIDI_TRACKS (512) caps checked
before session mutation, and collapse consecutive equal tempo events.
main split crates/mix/src/lib.rs: the clip-FX gain clamp now lives in
clips.rs and the send-level automation clamp in automation.rs (via
crate::SEND_LEVEL_MAX_DB). Adds tests for the send-automation clamp and
the load-time sanitize clamp (#884).

A 10-sample fade-out was already shorter than the processed clip, so the
fade-out clamp went untested. Use 40, as CodeRabbit suggested.
