Regression: socket_addrinfo_lookup(null) soft TypeError — Zend Deprecated+false (ext/sockets/sockets.c)

Problem

Without declare(strict_types=1), Zend emits E_DEPRECATED for null $host, then returns false. VM rejects with TypeError via VmString::coerceTypedStringBuiltinArg in ext/sockets/socket_addrinfo_lookup.php.

Under strict_types=1, both sides TypeError (OK). Sibling soft-null socket slices: #30313–#30316 / closed #30319–#30321.

Repro (2026-08-11, Zend 8.2.32 / master 7b9d9a1fef VM)	Zend 8.2	VM
socket_addrinfo_lookup(null); (no strict_types)	Deprecated + false	TypeError: Argument #1 ($host) must be of type string, null given

php-src reference

• php/php-src ext/sockets/sockets.stub.php — socket_addrinfo_lookup(string $host, ?string $service = null, array $hints = []): array|false
• php/php-src ext/sockets/sockets.c — PHP_FUNCTION(socket_addrinfo_lookup) / host Z_PARAM_STR (null → Deprecated + coerce)

PHP implementation target

• ext/sockets/socket_addrinfo_lookup.php — replace always-strict VmString::coerceTypedStringBuiltinArg with frame-aware soft path (stringBuiltinArgForFrame / same pattern as Regression: socket_connect(..., null) soft TypeError — Zend Deprecated+Warning+false (ext/sockets/sockets.c) #30316 socket_connect address)
• PHP-in-PHP only; no new C

Repro

./script/docker-exec.sh -- bash -lc 'cat > /tmp/socket_addrinfo_lookup_soft_null.php <<'"'"'PHP'"'"'
<?php
error_reporting(E_ALL);
try {
    var_export(socket_addrinfo_lookup(null));
    echo "\n";
} catch (Throwable $e) {
    echo get_class($e), ": ", $e->getMessage(), "\n";
}
PHP
php /tmp/socket_addrinfo_lookup_soft_null.php
php bin/vm.php /tmp/socket_addrinfo_lookup_soft_null.php'

Done when

• Soft socket_addrinfo_lookup(null) matches Zend Deprecated + false
• declare(strict_types=1); socket_addrinfo_lookup(null) still TypeErrors
• Compliance/repro guard under test/compliance/cases/ or test/repro/
• php-src-strict; VM(/JIT when implemented) agree

Merged #30366 — soft socket_addrinfo_lookup(null) → Deprecated+false; strict still TypeError. Verified: issue repro + phpunit --filter SocketAddrinfoLookupSoftNullVMTest (2 OK).
