123 reject chain glyph introduces value

// Glyph discipline (KORU103): `|>` CHAINS a step (an invocation, or a `_`
// discard) — it never introduces a bare VALUE. The resume value of a `-> T`
// effect is PRODUCED with `->`, not piped with `|>`. `! ask _ |> 42` was the
// old loose spelling; it must now be `! ask _ -> 42` (cf. 400_116). Twin of the
// `=>` rejection (KORU102, 400_122).
