.key_for(symbol) ⇒ Object

Locals key on ‘decl_span`; module-level symbols on `[module_name, name]`. NOTE: when `:type_annotation` refs land they may point at a `Symbol::Variable` that’s a type variable, which would collide with value-level locals under ‘[:local, decl_span]`. Revisit the keying scheme then —likely split into `[:local_value, …]` vs `[:local_type, …]`.
