Initial release: Miracast Enabler KernelSU module v1.0.0

Enables Wi-Fi Display (Miracast) on Pixel phones where Google
disabled it in software. Uses fabricated overlays, system properties,
and sysconfig XML. Includes WebUI for KernelSU manager.

Tested hardware: Pixel 10 Pro Fold (rango), Tensor G5, BCM4390.
