Problem
array_walk_recursive matches Zend on VM and JIT, but thin AOT segfaults after a successful build (happy path and null). Sibling of open #26969 (array_walk AOT segfault). Probed 2026-08-04 @ fb10b03c1.

- AOT/JIT walk-recursive lowering in
ext/standard + lib/JIT/ (PHP helpers; align with array_walk fix)
- PHP-in-PHP; no new C runtime branches
