record produce string fields

// Pins string-typed record-return field lowering: `-> { skip: string, ... }`
// must lower `string` to the host text type in the emitted `Output` struct
// (the string-surface-type `lowerZigType` reaching record-return fields). Last
// piece of the `! config -> { skip, trivia }` grammar-config shape — record
// produce and `: bind` consumption already hold.
