per_aggregate_dataclass_promotion

v1

Why this iteration: Lifted from conductor/code_styleguides/type_aliases.md §2.5 — the per-aggregate promotion rule codifies that any sub-aggregate with stable distinct fields must be its OWN @dataclass(frozen=True, slots=True), not a shared mega-dataclass. Source: conductor/code_styleguides/type_aliases.md §2.5 ("When the role has stable distinct fields, promote it to its OWN dataclass")
