Options > Click set a flag but nothing rendered sound, so a click track
was silent. The mix engine now synthesizes a short blip on every beat of
the tempo map (accent on beat 1), using the click.* settings from
Setup > Click/Countoff, and sums it after the master fader.
The metronome is opt-in per engine: only live playback enables it.
Offline renders (bounces, stems, exports) leave it off so the click is
never printed into a file.
Also: midi_to_hz moves from the engine demo into soundcraft-dsp so the
mix and demo share one tuning formula.

Double-clicking the tempo ruler opened a number dialog whose command was
built as "event.tempo@<position>". No such command exists, so OK failed
and nothing changed. The position was also never passed, so a change
would have landed at the session start.
Add a TempoChange dialog that carries the position and runs
event.tempo with bpm and at. Add an engine test that a tempo change at a
position is applied there.

There was no way in the app to choose a CLAP, VST3 or Audio Units instrument,
or to open an instrument's editor:
- the insert menus leave instruments out;
- an instrument was only set by track.new;
- the Mix window's INSTRUMENT row looked for instrument inserts rather than the
track's instrument;
- plugin windows opened only for insert slots.
Changes:
- mix.instrument {track?, plugin} sets an instrument track's instrument, with
the plugin's default parameters, and is undoable. It refuses effects and
other track kinds.
- The INST label on an instrument track's header opens an instrument menu: the
current instrument and its editor, then the built-in, CLAP, VST3 and Audio
Units instruments, by vendor.
- The Mix window's INSTRUMENT row shows the track's instrument. A click opens a
hosted instrument's plugin window, and a right-click changes it.
- Plugin windows open for the instrument slot, with only the editor button,
because the bypass, preset and parameter commands address insert slots.
They no longer derive a slot letter for the instrument slot.

The Mix window's insert menu listed each format's plugins as one flat column.
With many installed (53 VST3 and 95 Audio Units effects on a composer's Mac)
it ran past the bottom of the screen and egui menus don't scroll, so the lower
entries couldn't be reached. CLAP, VST3 and Audio Units now open one submenu
per vendor, as Pro Tools does when plug-in menus are organized by manufacturer,
and every list scrolls within the screen.
Choosing an Audio Unit did nothing: the engine's plugin lookup, which
mix.insert uses, covered built-in, CLAP and VST3 plugins only, so "au:" ids were
"unknown plugin" and the UI dropped the error. The lookup now includes Audio
Units (the engine depends on soundcraft-au-host, like the mixer and the UI), and
the menu shows a failed insert in the status bar.

Testing on macOS showed that the exit-handler fallback comes too late for a
plugin that has been used: with HALion Sonic inserted on a track, its bundleExit
segfaults, and both the app (on quit) and soundcraft-cli (after a bounce) exited
with 139. A plain scan was fine. Exit handlers run in reverse order of
registration, so state the plugin set up while in use is presumably torn down
before the host's handler runs.
soundcraft_vst3_host::shutdown() runs the module exits up front, and
soundcraft_engine::shutdown_plugin_hosts() calls it. The app calls that once the
event loop has returned (the player and its plugin instances are gone by then),
and the CLI once its subcommand has. The exit handler stays as the fallback for
other exits, such as test binaries.
The fixture can now set up state lazily the way such plugins do
(VST3_FIXTURE_LATE_STATE), and module_exit_shutdown checks both sides in child
processes: with shutdown() the exit is clean, with only the exit handler the
fixture reports the late teardown. Contract violations now end the process with
status 3 instead of an abort, so that expected failure leaves no crash report.

Video (new standalone crate soundcraft-video):
- Pure-Rust H.264 (Baseline/Main/High), ProRes (all flavours) and Motion JPEG decoding with
ISO-BMFF demux, adapted from FilmCraft's crates; fuzzed with mutated/truncated movies
- TrackKind::Video with ClipContent::Video referencing Session.videos; file.import_video adds
the picture track and the movie's audio; relinking on open; video.offset/online/list
- Video and Video Universe windows, thumbnails on the timeline, background decoding
Third-party plugins:
- Plugin state (CLAP state ext, VST3 component + controller state) saved in sessions
- Hosted instances created, state-loaded and dropped on the UI thread, never the audio thread
- Plugin editors: floating CLAP GUIs and VST3 views on macOS (verified with Melodyne)
- New isolated FFI crate soundcraft-au-host: Audio Units on macOS (effects and instruments,
parameters, latency, MIDI, ClassInfo state), wired into the mixer and plugin browser
UI: Window > Renderer (speaker layout with live levels and object positions), Window > UI
Customization (interface scale, reduce motion), Window > Configurations > Auto-Update.
Fix: saturating sample-index math in clip rendering (hostile stretch values overflowed).
