docs: record physical-GPU integration mechanism and refresh project status
- add docs/03-architecture/08-physical-gpu-integration.md: interfaces that
exist, mechanism options A-E, chosen path (module-owned GPU driven through
its real GSP firmware), sharing policy, decision record
- update 06-host-module-and-hybrid-model, 02-practical-challenges, system
overview, known-knowns, docs/README reading order and CUDA-side docs to
match
- correct stale engine-topology/COPY14 blocker claims across the tree
- add STATE-CURRENT.md as the dated public status snapshot
