feat(rembg): add RemoveBG Studio - native background removal app

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.

+.SYNOPSIS
+  Fetches the Microsoft WebView2 SDK (headers + x64 loader libs) into
+  native/third_party/webview2/, without needing NuGet or vcpkg installed.
+
+  The SDK is downloaded directly from nuget.org (same package vcpkg/NuGet
+  would fetch), unpacked, and only the pieces the CMake build needs are
+  copied out. Safe to re-run — skips work if already present unless -Force
+  is passed.
