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.

Main routes viewer scrolling through viewer_scroll, so a raw-event scrub fought the wheel zoom. With general.viewerWheelScrubbing on, an unmodified wheel steps frames and the rest of that notch does not zoom or pan. The preference stays off, so the wheel still zooms.
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.
