Plan the `race` async deliverable (roadmap A1): a structured first-wins over
the M:1 `Task` layer, returning a comptime-synthesized tagged-union mirroring
the input named tuple's labels. Identifies the one net-new compiler primitive
needed — `pointee($P: Type) -> Type` (project `*Task(A)` → `A`); everything else
(tuple reflection, union synthesis, the suspending runtime) is already in place.
Issue 0196: a named-tuple type ALIAS (`NT :: Tuple(a: i64, b: bool)`) loses its
structure — field access and reflection both fail on the alias, while the inline
and `$T`-type-parameter forms work. Not on the race critical path (race reflects
a tuple type parameter), filed for tracking.
