feat(primitives): kei-artifact typed handoff pipeline (BMAD-style doc passthrough)
- kei-artifact Rust crate (25th): schema registry + artifact store + SHA-256 id + chain walker
- 5 schemas (JSON Schema 2020-12 strict): spec / plan / patch / review / research
- Manifest extension: optional produces_artifact + expects_artifact per handoff (non-breaking)
- Validator extension: KNOWN_ARTIFACT_SCHEMAS whitelist check + 4 new tests
- 3 kei-* manifests updated with typed handoff (architect→code-implementer→critic chain)
- compose-solution phase-5 cross-ref to kei-artifact
Tests: 189 Rust workspace (was 167, +22 artifact tests) + 24 assembler (was 20, +4 validator tests)
