New src/starkernel/usb/ subsystem directory (added to both LOADER_SRCS_BASE and KERNEL_SRCS_BASE wildcards in Makefile.starkernel, matching the existing virtio/*.c pattern). xhci_find_and_map() locates the controller via the already-generic pci_find_first(), enables it, maps BAR0 via the already-generic pci_map_bar(), and fills in all four register-region pointers (cap/op/runtime/doorbell) plus max_slots/ max_ports/max_intrs from HCSPARAMS1 -- ready for controller bring-up (2c) to consume directly. No pci.c extension needed, per 2a's finding that PCI discovery here is ID-based lookup (already generic), not class-code scanning. Verified: clean standalone syntax check, full amd64 kernel build with zero warnings, live boot still reaches POST 1012/0/0 unaffected (nothing calls xhci_find_and_map() yet, so this is purely additive).

capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.

Block namespace
Block ranges are shared across all loaded capsules — collisions cause silent word-definition overwrites.
| Range | Owner |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |
