# Package the Windows release bundle into a versioned zip.
# Usage: powershell -File tool/package_windows.ps1 [-SkipBuild]
# Output: dist/watch-together-<version>-windows-x64.zip containing one
# top-level folder with watch_together.exe, its DLLs and data/ as built,
# plus update.bat (runs watch-together-server.exe --upgrade) and
# watch-together-server.exe (dedicated server, `dart compile exe` of
# packages/server/bin/server.dart; both binaries stamped with APP_VERSION).
# Same layout as tool/package_linux.sh; the updater strips the top-level
# folder.
# Needs: flutter on PATH, tar.exe (ships with Windows 10+, writes zip).
