Enable Slot command TRB submitted via a new xhci_submit_command()/ xhci_cmd_enable_slot(), ring doorbell 0, confirmed by a real Command Completion Event on all three architectures -- the first time this driver has written a TRB rather than only reading the Event Ring (2d). Added the Command Ring's previously-missing Link TRB (xHCI 1.2 spec sec 4.9.2) for wraparound correctness. Port Register connect/disconnect handling, slot-ID/context bookkeeping, Address Device, and the callback surface into Section U's code are still open -- this is the discriminating first step, not full 2e.

LithosAnanke — the bare-metal UEFI kernel that boots StarForth directly on
hardware (amd64/aarch64/riscv64). Built only via Makefile.starkernel; the
only valid acceptance test is the three-arch QEMU boot (see
.claude/CLAUDE.md), never make test.
kernel_main.c— kernel entry point, driving the boot milestones (console init, PMM, VMM, interrupts, timers, kmalloc heap, VM bootstrap).repl.c— kernel REPL.doe_log.c— kernel-side DoE (Design of Experiments) metrics logging.
Subdirectories:
arch/{amd64,aarch64,riscv64}/— per-architecture support (APIC/GIC/ PLIC interrupt controller, timers, boot/ISR assembly).boot/— UEFI loader, ELF loading, kernel command-line parsing.capsule/— capsule birth/run/load/validate pipeline.hal/— hardware-abstraction-layer implementation (console, framebuffer, VT100, memory, host services).hash/— XXHash64 content-addressing implementation.math/— kernel-build Q48.16 fixed-point arithmetic.memory/— physical/virtual memory managers and the kernel heap.pci/— PCI bus enumeration.virtio/— VirtIO block device driver.vm/— kernel VM subsystem (bootstrap, core interpreter, parity logging, capsule arena).
