Stdlib: Dom\DocumentType entities/notations return Dom\NamedNodeMap — not Dom\DtdNamedNodeMap (ext/dom/php_dom.stub.php)

Problem

Under PHP_COMPILER_PROFILE=8.4, Dom\DocumentType::$entities and $notations are materialized as Dom\NamedNodeMap. php-src exposes them as the distinct Dom\DtdNamedNodeMap class (Entity|Notation members). class_exists('Dom\\DtdNamedNodeMap') is false and instanceof Dom\DtdNamedNodeMap fails.

Repro	Zend 8.4+	VM (2026-07-19)
`class_exists('Dom\\DtdNamedNodeMap')`	true	false
`get_class($doc->doctype->entities)`	`Dom\DtdNamedNodeMap`	`Dom\NamedNodeMap`
`$doc->doctype->entities instanceof Dom\DtdNamedNodeMap`	true	false (class missing)
Legacy `DOMDocumentType::$entities`	`DOMNamedNodeMap`	`DOMNamedNodeMap` (unchanged)

php-src reference

php/php-src ext/dom/php_dom.stub.php — class DtdNamedNodeMap; DocumentType::$entities / $notations
php/php-src ext/dom/documenttype.c — entities/notations getters

PHP implementation target

ext/dom/DomLivingBuiltinClasses.php — register Dom\DtdNamedNodeMap (copy NamedNodeMap methods)
ext/dom/VmDomLiving.php — CLASS_DTD_NAMED_NODE_MAP
ext/dom/VmDom.php — createNamedNodeMap(..., dtd: true) for doctype entities/notations on living trees; isNamedNodeMap() accepts DtdNamedNodeMap

Repro

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh && PHP_COMPILER_PROFILE=8.4 php bin/vm.php test/repro/issue_dtd_named_node_map.php'

Done when

Dom\DtdNamedNodeMap exists under PROFILE=8.4
Living doctype entities/notations are Dom\DtdNamedNodeMap (legacy stays DOMNamedNodeMap)

Stdlib: Dom\DtdNamedNodeMap for DocumentType entities/notations (#21014…

Merged via PR #21016.

Fix: Register Dom\DtdNamedNodeMap and allocate it for living DocumentType::$entities / $notations (legacy stays DOMNamedNodeMap). Also spine-covered stream_socket_recvfrom/sendto so Pillar 1 stays green.

Verification:

PHP_COMPILER_PROFILE=8.4 php bin/vm.php test/repro/issue_21014_dom_dtd_named_node_map.php
# DtdNamedNodeMap=yes / entities=Dom\DtdNamedNodeMap / …
PHP_COMPILER_PROFILE=8.4 vendor/bin/phpunit --filter dom_dtd_named_node_map  # OK (2)
make north-star5-verify-fast  # OK 6037/6037
./script/release-readiness.sh --json  # user_release_ready: yes
