Two gaps that would each have undermined the update flow on release day. The update check polled /releases/latest, which GitHub defines as the most recent NON-PRERELEASE, non-draft release. Ship a version with the pre-release box ticked and it becomes invisible: no notification, no update button, on any platform, with nothing in the logs to explain it. StemDeck has always published even its alphas as normal releases (v0.8.0-alpha.17 has prerelease=false), which is the only reason this has not bitten yet -- it was a trap waiting on someone ticking a box. Now polls the releases list and takes the newest non-draft, so it is correct either way. Drafts stay excluded: they are already invisible unauthenticated, and a maintainer should not be offered a release whose assets do not exist yet. windows-check.yml and macos-check.yml now also run on pull requests that touch desktop/src-tauri/**, not workflow_dispatch only. This PR added roughly 600 lines of mostly cfg-gated Rust across two commits and every CI check passed without compiling a single line of it; the comment at the top of windows-check.yml notes that exact gap already shipped a broken Windows build in v0.11.1's first release attempt. Scoped by path so the self-hosted runners see no extra load from the majority of PRs, which never go near src-tauri. This also gets the macOS branch compiled for the first time. Local verification covered Windows and Linux, so the cfg(not(any(windows, linux))) arm of the three updater commands has never been near a compiler.
