ps5upload/scripts/install-windows.ps1

# install-windows.ps1 — one-shot dev environment bootstrap for Windows 11.
#
# Idempotent: safe to re-run.
#
# Installs (via winget where possible):
#   - Node.js LTS
#   - Rust (rustup-init)
#   - Visual Studio 2022 Build Tools w/ C++ workload (MSVC + Windows SDK)
#   - 7zip (used to extract the PS5 SDK zip in CI-clean way)
#   - Microsoft Edge WebView2 Runtime (preinstalled on Win11; verified)
#   - Repository-pinned PS5 Payload SDK (currently v0.44)
#     → $env:USERPROFILE\ps5-payload-sdk
#
# Run from an elevated PowerShell:
#   PS> Set-ExecutionPolicy -Scope Process Bypass -Force
#   PS> .\scripts\install-windows.ps1
#
# After it finishes, the script prints the env exports you need to persist via
# `setx` (or just paste into the current shell) so `make build` and `make run-client`
# work in any new terminal — assuming you have GNU Make available (Git Bash, MSYS2,
# or `winget install ezwinports.make`). Tauri itself doesn't need Make on Windows;
# the Make targets are convenience wrappers that shell out to npm/cargo.
