docs: add the full-system picture and interaction/scheduling diagrams
- new 03-architecture/09-full-system-picture.md: end-state map, GSP boot,
guest init, RPC lifecycle, memory model, work path (bridge and end state),
scheduling, isolation levels, KVM/mdev/VFIO, BAR/engine/channel/GMMU,
portability, performance model, implementation/test status
- new 03-architecture/10-interaction-and-scheduling.md: interaction inventory,
control-plane call path, msgq element lifecycle, channel pump, concurrency,
timing budgets, multi-tenant scheduling, teardown ordering, versioning
- README: mermaid system diagram replaces the ASCII block; reading list
extended and renumbered
- component docs: GSP boot sequence, mdev/VFIO lifecycle, end-state
interaction sequence; STATE-CURRENT links
