Package the desktop app for Arch, Debian and Windows

electron-builder produces j621-desktop_*_amd64.deb,
j621-desktop-*.pkg.tar.zst (zstd, lean Arch dependencies instead of the
Electron 2 era default set) and a per-user NSIS installer cross-built with
wine. The launcher entry and Electron's desktopName now agree on
io.j621.desktop so window association works, and package metadata points
at the repository homepage and the non-commercial licence.

+It installs to `/opt/J621` with a `/usr/bin/j621-desktop` symlink and a
+`io.j621.desktop` launcher entry (`StartupWMClass` matches the shell's

+rights are needed to install or update it — but it is unsigned, so SmartScreen
+will warn, and it has not been smoke-tested on real Windows.

 ## Smoke test
 
 `npm run smoke` builds everything, runs Electron headless through `xvfb-run`
