WebClient: 3.44 webcodecs offline (#15722)
* feat(web): zero-readback WebCodecs video path Decoded VideoFrames from js/src/webcodecs.js are handed to Flutter via window.onVideoFrame and imported GPU-side with createImageFromTextureSource; any failure unregisters the hook so the JS side falls back to RGBA readback. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(web): load bundled terminal font when Google CDNs are unreachable In air-gapped deployments GoogleFonts.robotoMono() cannot download the terminal font; when index.html signals offline mode, load the copy bundled with the web app under the family name google_fonts registers. Part of the fix for rustdesk/rustdesk-server-pro#996. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * ci: bump windows arm64 to Flutter 3.44.8, add web build patch script apply_flutter_3.44_web_patches.sh prepares a 3.44.x web build on top of the shared source patches: qr_code_scanner's web impl needs dart:ui_web for the removed platformViewRegistry, and flutter/web/fonts is refreshed to the font paths the 3.44 engine requests. The disabled build-rustdesk-web job runs it automatically once FLUTTER_VERSION moves to 3.44.x, and version-guarded 'Patch flutter' steps no longer fail when the guard does not match.
