Hojun-Cho ef7c0c1675 wcc: widen-push spills the float payload from X0, both stages ...

Widening a runtime f64 into a tagged slot pushed a stale AX as the
payload while the value sat in X0 — both stages shared the push bug
(float literals dodged it because TK_FLOAT loads AX too); the
divergent pop sides then produced different garbage. Spill the
payload from X0 (MOVSD) with the variant tag. Review item #49.

Both stages move in one commit: one emission contract; splitting
would leave the byte-id gates red between the halves.
