computer-use 0.0.4

Documentation and prompt-level change only: the screenshot description and the server instructions now tell a vision-capable model to prefer include_image=true for the observation step, and to use the sha1/changed_pixels_pct when it only needs to know whether the screen moved. Upgrade note: quit OpenCode before installing, because the running server holds its exe open. Wheel sha256 b8c9a17093fd163552bc4f595e4ae58d4b8a1a4f1b1c2adf3f2e3a82465ca403
