Detailed Description

The stored form of a weld annotation: the mask of target languages.

Usable bare (every language welder binds) or called with languages to scope it, like exclude_spec and weld_protected_spec:

struct [[=welder::weld]] A { ... };                     // every language
struct [[=welder::weld(welder::lang::py)]] B { ... };   // Python only

The bare form is the language-agnostic spelling a project reaches for when it wants a type to appear in whatever rods it builds — adding a backend later (a C# module beside a Python one) then needs no annotation churn. Scope it only where a type genuinely belongs to one language's surface.
