Proves AT-SPI2 can back the Linux ax_* ops on Debian/Ubuntu arm64:
ax_dump emits the same node JSON as the macOS agent, and ax_press/
ax_set_value/ax_focus map to AtspiAction/EditableText/Component. Ran
green on Debian 12 arm64, confirming the AT-SPI approach and the X11
screen-coordinate assumption. De-risks docs/LINUX_VM_AX_AGENT.md.
