Controller+ for Windows — local preview

Run controller-plus.exe to open the companion and scan its QR with your phone.
No separately installed Node runtime is needed.
Xbox 360 emulation uses ViGEmBus directly; no ViGEmClient.dll is needed.
If prompted, choose Install the Xbox controller driver on the owner page, approve
the Windows administrator prompt and finish setup. The original official signed
ViGEmBus 1.22.0 installer is bundled. Restart Windows if setup requests it.
Without ViGEmBus, an installed vJoy driver can provide DirectInput controllers.
Arrow keys and WASD work without a gamepad driver.

Windows bus calls, driver installation and game rumble still need Windows testing.
The companion executable is a local unsigned build, not a store-approved release.
Use --self-test for a packaged asset/helper check. Use --headless --json for local
integration testing; keep its owner URL private.
