Feedback on standard Android touchpad capture for the native display #98

I'd like feedback on adding mouse and touchpad capture to DroidVM's native display. The implementation is in #95.

It uses Android's public pointer capture API and handles both system-translated relative events and raw touchpad contacts. It uses the existing VM input path and has no vendor or device-model checks. The capture itself does not require a root input helper.

I tested the capture controls and two-finger scrolling in a Windows 11 guest on a Xiaomi Pad 8 Pro, and both worked as expected. I also verified capture with a USB mouse connected to the Android host. I'd be interested in hearing how it behaves on other devices.

Does this approach fit DroidVM's native display input design? Since #67 also touches pointer capture, how would you prefer the two changes to fit together?
