Windows 2.7.1 unsigned preview
Syncs the latest Mac-main feature work into Windows, fixes the Right Alt keycap after Home reactivation, and keeps the small top shortcut bar enabled by default with its Settings toggle. Adds a process-local Windows legacy-extension guard for the observed graphics-hook compatibility issue; global RTSS settings are unchanged.
Validation: all 220 UI cases pass, all 32 non-UI projects pass (10 explicit opt-in skips), 78 visual captures pass, both real RTX analysis journeys pass, and fresh native computer-use journeys pass. The exact Setup passed default and Unicode-path install/first-launch/uninstall checks on a disposable Windows runner. Release and extracted portable startup checks pass, and packaged payload/feed hashes agree.
This is an unsigned prerelease while Azure signing awaits an approved validation ID. The physical 3 AM wake acceptance test is scheduled, not yet proven. Stable-channel clients exclude previews. The Mac latest release and signed appcast are preserved.
