feat: Phase 3 — engine read path + runtime context builder

- Add buildThreadContext(headHash, cas) to workflow-runtime
- Expand extract phase to return { meta, contentPayload, refs[] }
- Add parseCasThreadNode() to workflow-cas for node type parsing
- Update createWorkflow to write ContentMerkleNode with artifact refs
- Tests: 4 pass (build-context + extract-refs)
- Biome format pass on all files

Refs #155, closes #158
