- 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
