Problem: app.scheduleTask(code, delay, true) queued the task and then
skipped it (eval_with_tasks: `if repeat { continue; }`), so repeating
tasks - what ScriptUI panels use for polling and refreshing - never ran.
One-shot tasks scheduled by handlers or in the Script Console never ran
either.
Fix: tasks live per script context (crates/script/src/tasks.rs) with a
due time. Frontends run the due ones every frame through the new
ScriptUi::run_tasks hook (the egui app does; agents and headless hosts
use the `script.runTasks` command). Script-host threads get a Tick
message, inline hosts (Script Console, web) run in their kept context.
A repeating task runs every `delay` ms until app.cancelTask, until it
throws (reported once, then cancelled), or until its owner goes: the
script's last window closing, or - for scripts without windows and the
console - the project being closed or replaced (ScriptUi::project_epoch).
Bounds: at least 50 ms between runs, at most 64 pending tasks per
script, one run per pass (no catch-up bursts), task code nested too
deeply is refused, the engine's loop and recursion limits apply. Ticks
only reach the hosts of the session that scheduled them.

Problem: ScriptUI controls never sent mouse events to scripts.
addEventListener("mousedown" | "mouseup" | "mousemove" | "mouseover" |
"mouseout" | "click") listeners never ran, so custom-drawn controls
(onDraw + mouse, as DuScriptUI builds them) could not react to the pointer.
docs/plugins.md listed this as missing.
Fix: scriptui.js builds a ScriptUI MouseEvent (clientX/clientY relative to
the target, button, detail = click count, screenX/Y, modifier keys,
getModifierState, stopPropagation, preventDefault) and delivers it in the
capture, target and bubble phases. addEventListener takes the capture flag.
The parent walk is bounded, so a script-made parent cycle cannot hang it.
Each published control lists the mouse events a listener wants
(Widget::mouse, inherited from containers). The new scriptui.mouse
command dispatches one event with clamped, finite values and rejects
unknown types and disabled controls. The egui ScriptUI view hit-tests the
pointer over script windows and docked panels, skipping covered layers and
windows blocked by a modal dialog. It sends mouseover/mouseout,
mousemove, mousedown/mouseup with click counts, and a click carrying the
pointer details in place of the plain click, so a checkbox still toggles
once. Handlers run under the existing script limits; a throwing listener
reports an error and the window keeps working.

EffectCraft's extension points compared with After Effects' (public
user guide and Scripting Guide) are now in docs/plugins.md, which
becomes "Plug-ins and extensions": scripts, ScriptUI panels and effect
plug-ins, with a short guide and an example panel for writing your own.
ScriptUI panels already came from `Scripts/ScriptUI Panels/` in the
settings folder, were listed at the bottom of the Window menu and
docked as tabs. What was missing: After Effects reopens the panels
that were open when it quit. Now the open panels are remembered in
`scriptui_panels.json` in the settings folder (a panel is added when
it opens and dropped when its tab or its script closes it; quitting
leaves the list), and `window.restoreScriptPanels` opens them again;
the desktop and web apps run it at start-up. A panel whose script is
gone or fails is reported and forgotten, and the others still open.
Where a panel was docked isn't kept, as workspace layouts aren't saved
between launches.
Gaps recorded in plugins.md and gaps.md G8: the Startup and Shutdown
script folders, keyboard shortcuts for scripts, ExtendScript's
`#include` / `#target` directives and `.jsxbin`.
Test: open_panels_open_again_at_the_next_launch (fails before: no
restore command), a_panel_dropped_in_the_folder_is_listed_and_opens_as_a_panel
(script), panels_open_at_quit_dock_again_at_launch (UI: the restored
panel docks with its controls; closing the tab forgets it).
