WINQ-EMU r21 runtime

WINQ-EMU r21 runtime component and corresponding source archives for the next signed Try Omarchy app release. This is not a standalone launcher or a new app version.

Built from the source-locked recipe at commit 8ec4033826e09cbd4c833c059bb0fd1517f18857 (the same tree as master at a02465f) in Runtime run 37135317236. SHA256SUMS covers both archives. r21 opens Windows playback and recording at each device's own sample rate, keeps precision touchpad scrolling smooth instead of rounding it to whole wheel clicks, and checks the host GPU driver's exact image import support before sharing images with it.

The currently published v0.8.0 app pins r20c. The next signed app release will pin r21.
