• Windows x64 joins the release pipeline as a portable ZIP (ufo-mothership-x64/ufo-mothership.exe + README.txt), served at https://ufo-mothership.alienz.ooo/windows/x64/latest.zip and listed in version.json under platforms.windows-x64. First pass only — no tray UI, no MSI installer, no code signing (SmartScreen warns on first launch), and the Bun binary is a console target so a cmd window stays open while it runs. Proper windowed build + signing cert + MSI are follow-ups.
• Landing page learned a Windows row and a UA sniff that swaps the primary CTA to the Windows ZIP when the visitor is on Windows.

Changed

• apps/server/src/main.ts data-dir detection now also recognises Windows user homes (C:\\Users\\X style), so the Windows build writes its data under %USERPROFILE%\\.ufo\\data instead of falling back to the container default /data. The isUnixyUserHome helper was renamed to isUserHome to match the broader reality.
