- startup/client.lua now prompts on first run: asks if a dropper is next to the computer, and if so, which side it's on - Saves config to .dropper_config (JSON with dropperSide, redstoneSide, enabled) - Only launches dropperController if dropper is enabled - dropperController.lua reads .dropper_config for its sides instead of hardcoding 'back' - Delete .client_setup to re-run the setup wizard
