Stdlib: get_object_vars() on backed enum case — name/value array not TypeError (ext/standard/var.c)

Problem

Zend get_object_vars() on a backed enum case returns the pseudo-properties name and value (strings/scalars). This compiler rejects the call with TypeError because enum cases are still materialized as backing scalars in many paths (#8746).

Framework debug/dump code expects enum cases to behave like objects for introspection.

php-src reference

• php/php-src ext/standard/var.c — PHP_FUNCTION(get_object_vars)
• php/php-src Zend/zend_enum.c — enum case object properties

Repro (failure today)

<?php
enum E: string { case A = 'x'; }
var_export(get_object_vars(E::A));

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
php repro.php
php bin/vm.php repro.php 2>&1 | head -4
'

Runtime	Output
Zend	array ('name' => 'A', 'value' => 'x')
VM	TypeError: get_object_vars(): Argument #1 ($object) must be of type object, string given

Scope (this repo)

Area	Path
VM	ext/standard/get_object_vars.php + enum object path in VmReflection / EnumCaseSupport
Depends	Enum case must be TYPE_OBJECT or accepted enum wrapper (#8746)
Tests	test/compliance/cases/stdlib/get_object_vars_enum_case.phpt
Matrix	script/capability-matrix.php note if VM-only initially

Done when (php-src-strict)

• Repro var_export matches Zend for backed enums
• Unit enums: empty array or documented parity per php-src version in Docker image
• ./script/ci-fast.sh --filter GetObjectVarsEnum green
• No LogicException for user-facing TypeError mistakes
