P2 Badge Remove undefined name from module all

MolecularWeight is listed in __all__ but this module does not define or import it, so from bioetl.domain.value_objects.molecular_descriptors import * now raises AttributeError at import time instead of succeeding. This makes wildcard imports and any tooling that trusts __all__ (e.g., auto-doc generators) fail; the export list should only contain symbols actually provided by this module.
