feat: implement ADB wrapper and device management backend

Adds full ADB client, device manager, static DeviceInfo fetcher, and
live DeviceLiveStats poller. Exposes ListDevices, ConnectDevice,
DisconnectDevice, GetDeviceInfo, GetDeviceLiveStats as Wails-bound
methods with a 1s devices:changed event loop. Bundles ADB binary
infrastructure via //go:embed all:bin with runtime fallback chain.
