// Comptime TUPLE metaprogramming — `define` constructs a tuple and `type_info`
// reflects one, completing the reflect/construct triad (enum 0619, struct 0622,
// tuple here). Tuples are POSITIONAL, so `TupleInfo` is just a `[]Type` (no field
// names). Two paths:
//   1. Programmatic build: `define(declare("Pair"), .tuple(.{ elements = … }))`.
//   2. Round-trip: `define(declare("TripleCopy"), type_info((i64, bool, f64)))`
//      reflects a source tuple type INTO a `.tuple(TupleInfo)` value and
//      reconstructs it — no literal element list.
