Mirrors upstream build.yml: the windows/386 leg uses a Win7-patched Go
(.github/setup_go_for_windows7.sh — MetaCubeX/go reverts of the Win7
removals) so the binary runs on Windows 7. Drops with_naive_outbound for
this leg (cronet-go has no windows/386 build); the rest of LX_TAGS
compiles for 386. Archive: sing-box-<ver>-windows-386-legacy-windows-7.zip,
matching the launcher's singbox-launcher-win7-32 (also 386).
