feat: config field in /cypher/execute — node-level component override

- /cypher/execute now accepts separate `config` field:
  {node_name: {component: "cmp_19e62efd", ...staticParams}}
- graph-builder reads config[node].component to override componentId
  (supports cmp_ hash, rec_ hash, or canonical_id)
- config[node] other fields become node.data (static params merged at runtime)
- acr run now sends workflow.config as separate `config` (not flattened into context)
- context is now only --input dynamic params
