Boot a real Linux inside QEMU and confirm that simulated USB/IP devices
work against a real kernel (vhci-hcd + cdc_acm):
- Add examples/demo.rs: a single server exporting a HID keyboard and a
CDC ACM serial device on port 3240.
- Add scripts/qemu/: build a minimal initramfs (host kernel + busybox +
usbip tool + demo server), boot it in QEMU, attach the simulated devices
over 127.0.0.1, and verify:
* the serial port emits 'a' (0x61) -> SERIAL_TEST
* the keyboard generates a KEY_1 input event -> KEYBOARD_TEST
- Add .github/workflows/qemu.yml to run this in CI (KVM when available,
TCG fallback otherwise), uploading the serial console log as an artefact.
