 * Minimal test bootstrap — stubs the WordPress functions used by the classes
 * under test so they can be exercised in plain PHP without a WP test install.
 *
 * This is intentionally NOT a full WP_UnitTestCase harness. It exists so the
 * targeted unit assertions in tests/unit/ can verify guard behavior, constant
 * shape, and args payload shape on CI (PHP lint job) without introducing a
 * PHPUnit + wp-env dependency. A proper integration test harness is a
 * follow-up (see CHANGELOG 0.2.0 notes).
