feat: add Opus autorun script and grid single-click for touch

- Add autorun/startup.lua for Opus package integration:
  - Detects role from config files (.manager_config, .client_config, etc.)
  - Registers reboot listener as kernel hook
  - Launches program via shell.openForegroundTab()
  - Client role also opens dropperController in separate tab

- Override grid eventHandler on actionable grids (itemGrid, smeltTab,
  craftTab) to emit grid_select on single mouse_click, enabling
  monitor touch to trigger actions immediately instead of requiring
  double-click
