numeraire.core.registry

Open registries over closed enums.

A minimal evaluator registry. Bundled native evaluators register here; external packages register the same way (directly or via the numeraire.methods entry-point group), so a new method/evaluator never requires editing core.

register_evaluator	Register evaluator under name.
get_evaluator	Return the evaluator registered under name.
available_evaluators	Return the names of all registered evaluators, sorted.
