refactor(workflow): migrate downstream packages to workflow-runtime (Phase 2+3)

- Verify createWorkflow in runtime has zero I/O imports
- Migrate agent-cursor, agent-hermes to pure workflow-runtime dependency
- Migrate agent-llm, util-agent, templates to dual dependency
  (runtime for types, engine for CAS/merkle/buildDescriptor)
- All 377 tests passing
