On Windows and Linux on_main_thread() always said yes, so any thread could
open, idle or close a CLAP editor, and an instance dropped on another thread
destroyed its editor there. CLAP allows clap.gui calls on the main thread
only.
It now uses the rule the CLAP host's Windows window code and the VST3 host's
module loading already use: the thread Rust names "main", where the app runs
its UI. The editor tests check that another thread, named or not, is refused
on every platform, and that a plugin dropped on another thread with its
editor open warns and leaves the editor instead of destroying it there (the
test plugin now allows that, and only that, at destroy).

* fix(ui): About credits tables fit without side-scrolling and their columns resize
The Contributors table and the Models table were egui Grids inside a
two-way scroll area: they opened wider than the dialog, so they scrolled
sideways, and Company and Model sat almost touching. Both are now
egui_extras tables. Each column opens at the width of its header and widest
cell, the spare width goes to the text columns (Name; Company and Model),
and every column edge can be dragged. Widening a column grows the table
like a spreadsheet, and only then does it scroll sideways; the header stays
put while the rows scroll. Counts and dates are right-aligned and every
cell is vertically centred.
The sorted column stays highlighted and its direction shows on the
toolbar's sort-order button, so headers no longer reserve room for an
arrow. The opening widths come from fit_widths, a pure function with unit
tests that a fitted table fills its room exactly and that only the text
columns give way when room is short.
The About dialog opens 820 points wide, so every column fits at its natural width.

* Let every credits column be dragged, and refit changed tables
The last column was egui's remainder column, which has no drag handle, so
it could only be resized from the edge before it. It is now an ordinary
column with its own handle.
A table keeps its column widths, so switching to a longer name left the
Name column at its old width and clipped the text. The table now goes
back to the opening fit whenever that fit changes: a longer widest cell
or a resized window. Dragged widths are dropped at that point.
fit_widths could overflow the room when one column hit the minimum,
because the other columns did not take up its share. Columns now give
way in proportion to their width above the minimum.

* Refit credits tables on what they measure, not the fitted widths
Comparing the fitted widths missed the case it was meant for. Name is the
only growing column, so a longer name takes its extra width from the
spare room and the fit comes out the same: a dragged Name width stayed,
clipping the longer name.
It could also drop dragged widths by accident. The fit comes from the
available width inside the scroll area, which scrolling can nudge, so
scrolling a widened table could reset it.
The table now compares the natural widths and the clip rect's width,
which scrolling does not move.

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.
* Tempo map: index tempo segments so tick/sample conversions are O(log n)
Every tick<->sample conversion walked all earlier tempo changes, so code
that converts many positions (MIDI import/export, the tempo ruler, score
layout, MIDI scheduling and controller chasing on the audio thread)
cost positions x tempo changes. A session or MIDI file with many tempo
changes and many notes or tracks could stall the engine or the audio
callback.
TempoMap now keeps the elapsed time at each tempo change (rebuilt on
every edit and on deserialize, never serialized) and binary-searches
the segment. MIDI scheduling also skips notes whose on and off both
fall outside the block before converting them.
* Tempo map: index a file's ticks with saturating subtraction
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.
When the aux/folder routing has a cycle, processing_order sorted the
auxes by a bounded feeder depth recomputed inside the sort key: each
evaluation re-searched every aux's output and sends against a growing
list of inputs, for up to eight hops, on every comparison. A session
with many auxes sharing buses made that cubic during audio sync.
Compute the same capped depth for every track at once: per hop, collect
the buses written by auxes reached so far, then mark the tracks reading
them. The result matches the old search (tested against it on a mixed
graph with cycles) and the sort uses it by lookup.
apply_params searched all of the track's automation lanes for every
stored insert parameter on every block, so a session with many
parameters and many lanes multiplied the two on the audio thread.
Collect the slot's lanes once per block, order them by parameter name
(keeping the first lane per name, the one the old search found) and
walk them alongside the sorted parameter map. The lane list reuses a
scratch buffer kept on the plugin slot.
convert wrote every file with bwf: None, so converting a Broadcast Wave file
dropped its bext: description, originator, dates and the time reference that
places it on a timeline. Pass the decoded bext on. The time reference counts
samples, so with --rate it moves to the output rate.
libloading 0.9 prints only "dlopen failed" ("dlsym failed", "LoadLibraryExW
failed") and keeps the dlerror text or the Windows error as the error's source.
The CLAP and VST3 loaders formatted the error alone, so a plugin built for a
newer glibc was reported as "dlopen failed" with no reason. Append the source.
* MIDI: index controller dedup by channel and kind
Remove Duplicate Notes rescanned every controller already kept at the
same tick for each incoming one. A session whose sequence holds one tick
with many distinct channel/controller pairs made that quadratic and
blocked editing. Track where each channel+kind sits at the current tick
in a map instead; the last event per key still wins.
* MIDI: tag dedup index entries with their tick instead of clearing per tick
Clearing the map on every tick change cost O(capacity) per tick after a
dense tick. Store the tick with each entry and treat entries from an
earlier tick as absent. Add an oracle test comparing against the
previous per-tick rescan on mixed-tick input.
The CLI installed no logger, so every log::warn! and log::error! was
dropped: a plugin that failed to load just vanished from
engine.clap_plugins with no reason. A small logger now writes warnings
and errors to standard error as `warning: <message>` and
`error: <message>`, like the CLI's own errors. The level is fixed:
RUST_LOG stays a desktop app variable.
Fixes#1304.
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.
* clap-host tests: scan a freshly created private directory for the garbage-file test
The test reused a PID-named directory under the shared temp dir after ignoring a
failed cleanup, then loaded every .clap candidate in it. Another local account
could pre-create that directory and plant a native library that the test runner
would load. Create the directory exclusively (mode 0700 on Unix) and fail
instead of reusing one that already exists.
* clap-host tests: create the garbage-file test directory beside the test binary, not under TMPDIR
An integration test creates send C while send A's window is open: the window moves to the new send
with its fader on screen, and undoing the send closes it. send_route_menu now opens the window only
after the send command succeeds, without the extra bool, and its comment says reassignment leaves
the window alone.
