Session::write_output (and refuse_export) is the one place that checks; Save Frame As
(PNG/PSD/EXR), Export Lottie, Save a Copy (+XML), Collect Files, Export Timeline (and its
pre-rendered movies), Export Template, Save Animation Preset, Export Guides and Export
Shortcuts write through it. The control channel's render.frame/ui.screenshot, MCP
render_frame and CLI render-frame --out check first (new query file.checkOutput for the
bridged cases). Save/Save As/auto-save are untouched.

File ▸ Export ▸ Adobe Premiere Pro Project… pre-rendered every layer Premiere can't show to
ProRes 4444 with the window waiting: minutes on a large comp, which Windows reports as not
responding. The export now runs as a job (Window ▸ Progress, cancellable, with per-layer
progress) when started from its dialog (`background: true`); without it, the command still
waits and returns the same result.

A slip on a layer with no source handles succeeded with `delta: 0` and nothing else, which
read like a no-op bug. The result now carries `requested` (seconds) and, per layer, `clamped`
when the source could not move that far.

Create Split Layers Above Original Layer became on by default in #2083, but a settings
file saved before then still holds `false` (every later save keeps it), so Split Layer
kept stacking the new layer below. Settings version 4 moves a stored `false` to the new
default once, like version 3 did for the old disk cache size; a choice made since stays.

A docked ScriptUI panel only ever saw its preferredSize: the host drew
it in a scroll area at max(dock, preferred) and the script's window never
learned the dock. scriptui.resize now gives a window a size: the script's
window takes it, lays itself out again and runs onResizing / onResize.
The dock host sends it whenever the panel's dock size changes, so
window.size is the dock's, as in After Effects.

Add Per-Corner Roundness to Rectangle Path: a checkbox (off by default) and four Pixels properties (top-left, top-right, bottom-right, bottom-left). New rectangles initialise the four values from their Roundness, so ticking the box keeps the shape; the radii are animatable and expression-driven.\n\nrect_radii() builds the path clockwise from the top-left with kappa quarter-circle arcs. Overlapping radii scale down like CSS border-radius; negative and non-finite radii are square; rect() delegates to it, so uniform roundness clamps to half the shorter side as before.\n\nLottie rc has one r: four equal static radii export as that value; mixed or animated radii export roundness 0 with a warning. Import puts r into the four per-corner values so ticking the box on an imported rectangle keeps the shape.\n\nTests: path geometry and clamping, rendered per-corner pixels, Lottie equal/mixed/checkbox-off export.
A drag that started on a script control stopped at the window edge:
moves outside were dropped and a release outside never reached the
control. While a button is held, the control it was pressed on now gets
the moves (with screen and control-relative coordinates) and the
release, wherever the pointer is, as in After Effects. Every MouseEvent
also carries buttons (held: 1 left, 2 right, 4 middle), so a handler can
tell a drag from a hover; scriptui.mouse accepts it too.
