Adds Setup/Data/Status stage TRB types and control bits (IDT, TRT, DIR) to xhci.h, and xhci_ep0_enqueue_trb()/xhci_ep0_get_device_descriptor() to xhci.c -- the first real control transfer this driver has issued. Follows the same enqueue-then-doorbell-once pattern as the Command Ring, operating on the EP0 Transfer Ring built during 2e's Address Device work. Setup Stage uses Immediate Data (parameter IS the 8-byte setup packet); Data Stage reads into a reused 18-byte device_descriptor buffer; Status Stage alone carries IOC, so exactly one Transfer Event signals transfer completion, correlated via a new pending_transfer_slot_id (same single-outstanding-operation pattern as connect/Enable Slot/Address Device). Automatically triggered once Address Device succeeds. Verified live via QMP hotplug, all three architectures, worked first try with identical results everywhere: idVendor=0x46f4, idProduct=0x0001, bDeviceClass=0x00 -- the class=0 confirms Mass Storage class detection needs the Configuration/Interface descriptor (2f's next item), not the device descriptor.

include/starkernel/
Headers for LithosAnanke, the bare-metal UEFI kernel (src/starkernel/).
Built only via Makefile.starkernel; gated by __STARKERNEL__ when shared
with hosted code.
uefi.h— UEFI protocol/type definitions consumed by the loader.elf64.h,elf_loader.h— ELF64 parsing and kernel-image loading.boot_info_offsets.h— struct-offset constants shared between the assembly bootstrap and the C boot path.arch.h,apic.h,timer.h— architecture init, APIC interrupt controller, timer (TSC/HPET/APIC, 100 Hz heartbeat).console.h,framebuffer.h,vt100.h— UART 16550 console, framebuffer driver, and VT100 terminal emulation over the framebuffer.pmm.h,vmm.h,kmalloc.h— physical memory manager (bitmap allocator), 4-level x86_64 paging, kernel heap allocator.pci.h,virtio_blk.h— PCI enumeration and the VirtIO block device driver (disk backend for the kernel block subsystem).capsule.h,capsule_birth.h,capsule_loader.h,capsule_run.h,capsule_vm_physics.h,capsule_generated.h— capsule system types, birth protocol, physics-runtime capsule bindings, and the build-time- generated capsule directory (seetools/mkcapsule.c).kernel_args.h,cmdline.h— boot-time kernel argument parsing (starforth.cfg/ command line).repl.h— kernel REPL.log.h,doe_log.h— kernel logging and DoE metrics logging.q48_16.h— kernel-build copy of Q48.16 fixed-point arithmetic.xxhash64.h— content-addressing hash used for capsule IDs.hal_memory.h— hardware-abstraction-layer memory interface.
Subdirectories:
hal/— top-level hardware-abstraction-layer interface.vm/— kernel VM subsystem headers (capsule arena, parity logging, bootstrap wiring).freestanding/— minimal libc-shim headers (assert.h,ctype.h,errno.h,inttypes.h,math.h,sched.h,signal.h,stdio.h,stdlib.h,string.h,time.h,sys/time.h,sys/types.h) for building shared VM code in the freestanding kernel environment, where no real libc is available.
