test(parparvm): update facade contract for ImageData.writeArgbBuffer delegation

Commit 364c239 ("fix(js-port): fade transition rgbBuffer write reaches
live ImageData") replaced HTML5Implementation.createImageData's
worker-side ``JavaScriptImageDataAdapter.writeArgbToRgba`` unpack-and-set
loop with a single host-side ``ImageData.writeArgbBuffer(...)`` round
trip, because the worker→host marshalling clones any returned
``Uint8ClampedArray`` for read-perf reasons (``hostResult`` in
browser_bridge.js) — so ``data.set(arr)`` on the worker-side
ImageData.data wrote into a phantom buffer and ``putImageData`` rendered
transparent black.

JavaScriptRuntimeFacadeTest still asserted the old delegation contract
via ``contains("JavaScriptImageDataAdapter.writeArgbToRgba(")``, which
no longer holds; the test was correctly catching the architectural
change. Update the assertion to look for ``.writeArgbBuffer(`` (the
new delegation point), with a comment pointing at the fade-fix commit
so anyone removing this delegation is forced to look at why the path
was moved host-side. The read direction
(``JavaScriptImageDataAdapter.readRgbaToArgb``) is unchanged.
