php-in-php: drop Context ensureMinimalUserStandaloneBodies always-on StringHtmlspecialchars — lazy at call sites

Problem

Context::ensureMinimalUserStandaloneBodies() still eagerly NestedJIT/links StringHtmlspecialchars on every thin AOT user-script init (hello-world / aot-smoke path), even when the script never calls htmlspecialchars:

• StringHtmlspecialchars::ensureStandaloneBodies → NestedJIT / bridge (HtmlspecialcharsJitHelper)

Same always-on NestedJIT vs Runtime ABI drift / cold-build surface class as closed #34631 / #34621 / #34612 / #34605 and open peer #34641 (StringTriggerError). Leftover Context NestedJIT vs Runtime ABI drift mints *.1 (#31894 / #32122).

Call site already StringHtmlspecialchars::ensureLinked before lookup (ext/standard/htmlspecialchars.php). Peer #34612 already lazy-dropped HtmlEntities / HtmlspecialcharsDecode for the same reason.

Repro	Zend 8.2+	AOT thin hello-world
echo "hi"; (no htmlspecialchars)	hi	must not NestedJIT htmlspecialchars ABI during init
echo htmlspecialchars('<');	&lt;	matches Zend via call-site ensureLinked

php-src reference

• php/php-src ext/standard/html.c — PHP_FUNCTION(htmlspecialchars)
• Peer: #34612 HtmlEntities/Decode lazy; #34641 StringTriggerError lazy

PHP implementation target

• lib/JIT/Context.php ensureMinimalUserStandaloneBodies — remove StringHtmlspecialchars::ensureStandaloneBodies
• Keep call-site ensureLinked in ext/standard/htmlspecialchars.php
• Update peer shrink keep-lists + ExamplesHelloWorldAotRegressionTest / HtmlspecialcharsDecodeRuntimeShrinkTest
• Unit shrink test + ./script/aot-smoke.sh 8/8

Repro

./script/aot-smoke.sh
./script/docker-exec.sh -- bash -lc 'echo '\''<?php echo htmlspecialchars("<x>");'\'' > /tmp/hs.php && php bin/compile.php -o /tmp/hs.bin /tmp/hs.php && /tmp/hs.bin'

Done when

• ensureMinimalUserStandaloneBodies does not call StringHtmlspecialchars::ensureStandaloneBodies
• AOT htmlspecialchars('<') still matches Zend
• ./script/aot-smoke.sh still 8/8
• Shrink unit test + peer keep-list updates
