php-in-php: drop Context ensureFullStandaloneBodies always-on StringGetenv/StringGetenvAll — lazy at JitEnv (ext/standard/basic_functions.c)

Problem

Context::ensureFullStandaloneBodies still NestedJITs __compiler_getenv / __compiler_getenv_all after the standalone-init phase (always-helper #20156). Thin hello-world and scripts that never call getenv() pay that NestedJIT during full standalone init — leftover Context NestedJIT vs Runtime ABI drift mints getenv.1 / getenv_all.1 (#31894 / #32122).

Call sites already ensureLinked before lookup:

• ext/standard/JitEnv.php — StringGetenv::ensureLinked / StringGetenvAll::ensureLinked (php-in-php: drop always-on Type __compiler_getenv / __compiler_getenv_all ABI shells (ext/standard/basic_functions.c) #32665)

Peer ensureFull drops: #35113 RandomBytes, #35099 ExceptionBridge, #35089 Utf8/Define/…, #35086 Stream*, #35065 Json/Offset, #35073 Assert/Gc.

php-src reference

• php/php-src ext/standard/basic_functions.c — zif_getenv

PHP implementation target

• lib/JIT/Context.php — remove StringGetenv::ensureStandaloneBodies / StringGetenvAll::ensureStandaloneBodies from ensureFullStandaloneBodies
• Document lazy-full on StringGetenv.php / StringGetenvAll.php
• Guard test peer #35113 shape
• No new runtime/*.c

Repro / verify

./script/aot-smoke.sh
./script/phpunit.sh --filter 'ContextFullStandaloneLazyGetenvShrinkTest|TypeDeadGetenvAbiRuntimeShrinkTest|StringGetenvRuntimeStandaloneTest|StringGetenvAllRuntimeStandaloneTest'
./script/docker-exec.sh -- bash -lc 'php bin/compile.php -o /tmp/hw.bin -r "echo \"hi\";" && /tmp/hw.bin'

Done when

• ensureFullStandaloneBodies does not NestedJIT getenv / getenv_all
• ./script/aot-smoke.sh stays 8/8
• Targeted phpunit filter green
• Hello-world AOT still prints hi
