Adds Slot/Endpoint/Input Control Context structs (32-byte layout only -- HCCPARAMS1.CSZ checked live and confirmed 0 against this driver's QEMU target; 64-byte contexts refuse rather than silently mis-laying-out), xhci_cmd_address_device(), and a new dev->connect_state (idle/await-enable-slot/await-address-device) sequencing Enable Slot and Address Device per connect. Input Context (what the command TRB's parameter points at) and Device Context (what DCBAA[slot_id] points at) are separate 64-byte-aligned allocations, lazily created once and reused across every connect -- single-device driver scope, no free path needed. A new EP0 Transfer Ring uses the same fixed-ring-plus-Link-TRB pattern as the Command Ring. Two facts checked live before writing any context code, not assumed: HCCPARAMS1.CSZ (32-byte, confirmed) and PORTSC.PED at connect time (already set -- PORTSC=0x00021203, SuperSpeed -- the test device self-enables via USB3 link training, so no port-reset state machine was needed this increment; USB2 would need one, untested). Both diagnostics also added console_puts/println-based hex logging (xhci_log_hex32()) -- console_println() only takes string literals, no formatted print existed on this driver's console path before now. Verified live via QMP hotplug, all three architectures, succeeded on the first attempt with no debugging needed: "enable slot succeeded" -> "address device command submitted" -> "address device succeeded" on every boot. Also fixes a FABRIC-2.md dependency-direction error from the previous commit (Address Device is 2f's prerequisite, not the reverse).
