Release builds: Intel disk images, a Windows bundle, and where to download them

launcher/macos/build.sh takes ARCH=x86_64 for Intel Macs — the Swift target
and the embedded Node follow (nodejs.org calls that one darwin-x64). The
default stays arm64.

launcher/windows/build.sh is new: the same payload plus Node for Windows,
checksum-verified against nodejs.org, and ProdDash.bat, which keeps the
server running and starts it again on exit code 75 — the admin page's update
restart — the way the macOS launcher does. No Windows launcher app yet.

The README's Run it section now points at the Releases page and the
ProdDash-releases repo that holds the files, one line each for Apple
silicon, Intel and Windows.
