On Windows 11 ARM64 the launcher forced the x86_64 (
win64) Chromium-for-Testing build and ran it under emulation, where GPU/rendering issues break screenshot capture. Chromium-for-Testing now publishes nativewin-arm64builds, so we resolve those directly.Changes
ResolveChromiumForTestingPlatform: mapswindows/arm64to the nativewin-arm64platform (waswin64).resolveLatestDownloadURL: drops thearm64 → amd64override; prefers the nativewin-arm64build and falls back towin64only when Chromium-for-Testing has no native stable build.Test_ResolveChromiumForTestingPlatformand awindows-arm64download-URL case.System-installed native Chrome/Edge/Chromium are already discovered via the existing
Program Files/LocalAppDatasearch, so no path changes were needed.
