php-in-php: drop Context ensureMinimalUserStandaloneBodies always-on CliArgvRuntime — lazy at CliArgvGlobalInit / compileToFile (#32122 class)

Problem

Context::ensureMinimalUserStandaloneBodies() still eagerly CliArgvRuntime::ensureStandaloneBodies on every thin AOT user-script init (hello-world / aot-smoke path), even though:

• compileToFile already CliArgvRuntime::ensureStandaloneBodies before __phpc_cli_store_argv for thin standalone
• CliArgvGlobalInit::{load,loadArgc,emitRefreshAfterStoreArgv} already CliArgvRuntime::ensureLinked before lookup
• JitGetopt already CliArgvRuntime::ensureLinked

Always-on during init is the same leftover NestedJIT / ABI-link surface class as closed #34812 (SuperglobalName) / #34807 (EnvLocal). Mid-{main} ensureLinked without insert-block restore orphans calls / fails Module.php:180 (#27317 / #34812).

CliArgvRuntime no longer NestedJITs CliArgvJitHelper (pure LLVM refresh); keep ABI in the binary via compileToFile + call sites — just not during ensureMinimal init.

Repro	Zend 8.2+	AOT thin hello-world
echo "hi"; (no $argv)	hi	must not eagerly link CliArgv during ensureMinimal
echo $argc;	1	matches Zend via call-site / compileToFile ensureLinked

php-src reference

• php/php-src ext/standard/basic_functions.c — $argc / $argv CLI SAPI
• Peer: #34812 SuperglobalName lazy; #34807 EnvLocal lazy; #34463 Type::initialize CliArgv drop

PHP implementation target

• lib/JIT/Context.php ensureMinimalUserStandaloneBodies — remove CliArgvRuntime::ensureStandaloneBodies
• lib/JIT/Builtin/CliArgvRuntime.php — save/restore insert block on implement() (peer MetaTags #27317 / #34812)
• Keep compileToFile thin ensure + ensureFullStandaloneBodies / bootstrap-aot
• Update peer shrink keep-lists + unit shrink test
• ./script/aot-smoke.sh 8/8

Repro

./script/aot-smoke.sh
./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
echo '\''<?php echo "hi\n";'\'' > /tmp/hw.php
php bin/compile.php -o /tmp/hw.bin /tmp/hw.php && /tmp/hw.bin
echo '\''<?php echo $argc, "\n";'\'' > /tmp/av.php
php bin/compile.php -o /tmp/av.bin /tmp/av.php && /tmp/av.bin'

Done when

• ensureMinimalUserStandaloneBodies does not call CliArgvRuntime::ensureStandaloneBodies
• Thin hello-world / $argc AOT still match Zend; aot-smoke 8/8
• Mid-{main} $argv ensureLinked restores insert block (no Module.php:180)
• Shrink unit test + peer keep-list updates
• No new lib/AOT/runtime/*.c

Parent / peers

• #32122 cold-build / *.1 mint class
• #34812 SuperglobalName; #34807 EnvLocal; #34463 Type CliArgv
