record produce named fields

// Pins named-field record PRODUCE + inline-produce (`: bind`) CONSUMPTION.
// `-> { a: i64, b: i64 }` lowers to a Zig struct literal, and the caller reads
// it back with `config(...): r |> ... r.a`. Guards the classification that
// routes `-> {record}` through the shared struct-literal path (parser.zig) for
// every emitter, and the `: bind` consumption of a bare-return record.
