110 generic struct basic

// RED PIN (type-system design walk, 2026-07-06/07). REWRITTEN from the
// dead generation: `~struct(Option<T>)` parametric grammar is banned
// (generics-are-a-comptime-library ruling, 2026-06-13; `<>` is the
// phantom channel). The intent — a parameterized type — survives as a
// STAMPED NAME: `#` marks a monomorphized type identity in the name
// itself (ruled direction 2026-07-06: layout-determining identity lives
// in the part that survives phantom erasure — the name).
//
// This pin claims ONLY: `#` is legal in a declared type name, and the
// declared type is emitted and usable (host side may see it as the
// Zig quoted identifier @"box#i64" — emission spelling PROVISIONAL).
// The stamping/family MECHANISM (who mints box#T for all T) is
// deliberately NOT pinned — that is the comprehension/generation
// design, still open.
