Controller And Keyboard Launching

Issue: https://github.com/aarmea/shepherd-launcher/issues/20

Prompt summary:

• Launching activities required pointer input.
• Requested non-pointer controls:
  • Selection via arrow keys, WASD, D-pad, or analog stick
  • Launch via Enter, Space, controller A/B/Start
  • Exit via Alt+F4, Ctrl+W, controller home
• Goal was better accessibility and support for pointer-less handheld systems.

Implemented summary:

• Added keyboard navigation and activation support in launcher UI grid.
• Added explicit keyboard exit shortcuts at the window level.
• Added gamepad input handling via gilrs for D-pad, analog stick, A/B/Start launch, and home exit.
• Added focused tile styling so non-pointer selection is visible.
