Adds crates/bcvk-qemu/src/usb_passthrough.rs: - detect_yubikeys(): walks /sys/bus/usb/devices, matches idVendor=0x1050 - require_yubikeys(): fails fast with clear message if none found - qemu_usb_args(): builds usb-ehci controller + usb-host device args - UsbHostDevice: vendorid/productid pair with QEMU arg formatter - Unit tests: 5 tests, all pure (no sysfs access) See docs/yubikey-passthrough.md for CommonVmOpts wiring instructions.

… lib.rs Assisted-by: Sauna (claude-sonnet-4-6)
… QemuConfig - Adds `usb_host_devices: Vec<UsbHostDevice>` field (defaults to empty via Default) - Adds `add_usb_host_device()` builder method - Emits QEMU USB EHCI controller + usb-host args in spawn() when list is non-empty Assisted-by: Sauna (claude-sonnet-4-6)
…impl - Adds `--yubikey` bool to `CommonVmOpts` (serde default = false for BCK_CONFIG compat) - In `run_impl`, calls `bcvk_qemu::usb_passthrough::require_yubikeys()` and registers each detected device with `qemu_config.add_usb_host_device()` - Fails fast if --yubikey requested but no Yubico device found on host Assisted-by: Sauna (claude-sonnet-4-6)
