MVP Functionality

Ideas for a first MVP:

• A GTK4 window
  • with selection of the product (SKU?) via Dropdown
    • for the first version, this should be Reform Keyboard (https://source.mnt.re/reform/reform/-/tree/master/reform2-keyboard-fw) and Reform Trackball 2 (RP2040)
  • Button for cloning/updating the repo for the product
  • Configurable radio buttons or dropdowns to select parameter value for the project.
    • For the keyboard there are two variables:
      • Variant: Standalone / Laptop
      • Language: US / Non-US
    • Applying the configuration should rebuild the firmware if necessary
  • Buttons with actions for executing build/flash/test scripts in the repo
    • for the keyboard, "Flash" should do this with sudo (!): https://source.mnt.re/reform/reform/-/blob/master/reform2-keyboard-fw/flash.sh
    • "Test" should show a new window with a list of keycodes that disappear once each key has been pressed at least once
  • a split area showing terminal output in realtime
