* fix(core): capture blur sizes its taps to the smear and weights them exactly
A fast move strobed at the default 16 taps (8 px steps on a 1560 px whip). With no
data-motion-blur-samples set, taps are now about one per 2 px of travel (2 to 128); an
explicit samples count still wins.
Canvas quantizes image globalAlpha to 1/255, so 1/n weights left coverage short (n = 104
summed to 0.81, a lighter card body). Each tap now carries a whole number of 1/255 units
that sum to exactly 255.

* feat(core): capture blur draws the movers from their own transparent layer
The crop came from a capture of the whole scene, so the backdrop under a see-through mover
smeared with it (a lighter box with the dotted background erased) and a glow or shadow
outside the mover's box was cut off, leaving a hard-edged box.
Each frame now captures the movers alone, everything else visibility:hidden, so a mover's
pixels carry their true alpha and no backdrop; the background capture is unchanged. The crop
grows by the mover's ink reach (box-shadow, text-shadow, filter, outline, measured during the
scan), so glows travel with it. Two paints per frame, as before.
The output is cleared on wrap instead of showing the previous wrap's last frame, since the
first paint is no longer a drawable sharp frame. Core's unpacked size budget goes to 3,950,000
for the new module.

* fix(core): capture blur finds callback-driven movers when events are on
The mover scan seeked with callbacks suppressed even where the root allows them, so a
composition whose motion lives in a timeline callback (a render(t) driven from onUpdate)
reported 0 movers and rendered sharp. With data-motion-blur-events="on" the scan now seeks
the way the frame reads do. Without it nothing changes: callbacks stay suppressed.
The no-movers finding in hyperframes check now names the attribute.
