C++ WebView2 host app driving a Python/rembg engine as a JSON-stdio
sidecar, with live before/after preview for images and video frames.
Also includes the original CLI (removebg.py) built on the same
core/ engine.
The WebView2 SDK is fetched on demand via
native/third_party/fetch-webview2.ps1 (wired into the Makefile)
rather than vendored, since it's ~15MB of prebuilt/generated
Microsoft SDK content. A Makefile provides make sync/build/run/clean
as the standard entry points.
Add tool description covering auto-detection behviour, the ComfyUI and
Ollama model payload, skip-if-present logic, build/run instructions, and
the Windows requirement.
