Adds an evdev/uinput-based input emulation backend for Linux that creates a virtual mouse/keyboard, bypassing Wayland restrictions. Useful as a fallback on systems without a working remote desktop portal (e.g. COSMIC). Rebased onto the build.rs cfg-alias mechanism (evdev / evdev_emulation) introduced after the original PR. The backend is preferred in the auto-fallback order when /dev/uinput is accessible and falls back cleanly to the other backends otherwise. Documents the udev-rule permissions setup in the README.

I want to start by saying I take no credit for the bulk of this work. I wanted to use lan-mouse, ran into issues because I use niri as my compositor everywhere, and stumbled upon the stale pull request from @samvv (#297) and decided to use Claude to resurrect it and hopefully get it merged. I have successfully tested it manually myself and have a wide variety of machines and operating systems I am happy to run some manual tests on if requested. I also only care that this change makes it in and am more than happy to shepherd it across the line.
