🟢 Approval recommended

The change is minimal and correctly adds a new catalog entry; the only feedback is a non-blocking best-practice suggestion about using a stable “latest” download URL.

Re-triggering CI: the underlying AppImage had a bug (winit's X11 keyboard support is dlopen'd at runtime and wasn't bundled/discoverable, causing a crash on launch). Fixed and re-uploaded to the same release asset URL.

[madtunebk]

Second fix: winit also dlopens core X11 client libs (libX11, libX11-xcb, libXcursor, libXi) at runtime, not just xkbcommon-x11 — the CI runner has none of them since it's not a desktop image. Bundled the full closure into the AppImage and re-uploaded.

[madtunebk]

Third fix: the bundled X11 libs were themselves copied from an Ubuntu 24.04 host (glibc 2.39) and required GLIBC_2.38, incompatible with the CI runner's Ubuntu 22.04 (glibc 2.35) -- same class of issue as the earlier GLIBC_2.39 binary problem, just for the bundled shared libs this time. Re-extracted them from an ubuntu:22.04 container instead (max GLIBC_2.34 now) and re-uploaded.
