Conversation
The `label_field` config used field values (e.g., role: "admin") as Cypher
node labels, which is semantically incorrect — labels should represent node
types, not property values. Now the last segment of `node_path` is used as
the node label (e.g., `"Patent"` from `{"Patent": [...]}`).
Breaking changes:
- `GraphConfig::label_field` field removed
- `GraphConfig::new()` no longer accepts `label_field` parameter
- `ArraySchema::recommended_label_field` removed
- `NodeFieldInfo::is_label_candidate` removed
New API:
- `GraphConfig::label()` — returns the derived label from `node_path`
