Define parameter presets as text and output a whole set by picking one
from a dropdown. Output slots are rebuilt dynamically from the preset
text, reusing the shared AnyTypeTuple for variable-length returns.
The preset dropdown uses a function-based options.values so it restores
correctly on reload and works through subgraph inputs. Connecting a
Primitive node is unsupported: ComfyUI copies the static server-side
INPUT_TYPES (empty for this dynamic combo) instead of the live widget.
