Glary-Bot 2b731a99fd Add API workflow JSON demonstrating ImageBlend channel-count fix
Adds a self-contained API workflow at
tests/inference/graphs/image_blend_channel_mismatch.json that exercises
the previously-broken RGB + RGBA blend case end-to-end:

  EmptyImage (RGB, red)        -> image1
  EmptyImage (RGB, blue)
    + SolidMask (0.5)          -> JoinImageWithAlpha (RGBA) -> image2
                                 -> ImageBlend (3ch + 4ch)
                                 -> SaveImage

The workflow uses no model checkpoints and runs in seconds on CPU. With
the fix it produces a 4-channel RGBA output (alpha preserved); the
previous behavior would have silently dropped the alpha channel via
node_helpers.image_alpha_fix.

Verified end-to-end against a local ComfyUI instance: workflow executes
successfully, output PNG is RGBA, center pixel is (127, 0, 127, 191) -
red and blue blended at 0.5 with alpha 0.5*1.5=0.75 (191/255).
