transform-build-mosaic-collage-with-transloadit

One-off justified mosaic photo collage (N local images -> single image) using the official `@transloadit/node` CLI. Uses the `/image/merge` Robot's `mosaic` effect to build a justified tiled layout with center-cropped photos, and downloads the result to an explicit output path via `--output`.
