The GTK embedder's OpenGL compositor uploaded the frame with the window's new
dimensions while its pixel buffer still held the previous size, so memcpy read
past the end of the buffer and the process died with SIGSEGV
(fl_compositor_opengl.cc). Upstream fix: flutter#187626, present in Flutter
3.47.7 but not in 3.44.7.
Linux builds now use /home/alhan/development/flutter-3.47.7; pubspec.lock was
re-resolved for Dart 3.13.5 and the new tool added its build/platform excludes
to analysis_options.yaml. dist/ carries the 1.6.3 package instead of 1.6.2.
