Backend custom-node model adapters
Backend integrations for non-standard workflow node formats live here.
Each adapter declares its node types, category hints, and fixed widget categories. Optional hooks can provide:
- custom workflow reference extraction;
- lightweight potential-reference detection;
- custom workflow path updates;
- existing-reference filtering;
- Loaded Models display adjustments.
Register new adapters in registry.py. Generic dictionary-backed model fields,
including nested_key, stay in the shared analyzer and updater because they are
not specific to one node package.
