php-in-php: drop Context ensureMinimalUserStandaloneBodies always-on EnvLocalRuntime — dead __compiler_env_local_* NestedJIT (peer #34769 / #34513)

Problem

Context::ensureMinimalUserStandaloneBodies still eagerly EnvLocalRuntime::ensureLinked (→ JitEnvLocalKernel NestedJIT of __compiler_env_local_lookup / __compiler_env_register_putenv + StringGetenv::ensureJitHelperCompiled).

Thin AOT hello-world NestedJITs that ABI on every compile even though no call site looks up __compiler_env_local_* anymore — getenv() / putenv() lower via StringGetenv / PutenvJitHelper / GetenvLookupJitHelper (#32665 / #23414 / #29313). Type always-on shells were already dropped (#32729 / #34513); Context ensureMinimal is the leftover always-on.

Leftover Context NestedJIT vs Runtime ABI drift mints env_local_lookup.1 (#31894 / #32122).

php-src reference

• php/php-src ext/standard/basic_functions.c — zif_getenv / zif_putenv (overlay is PHP helper SSOT; no C ABI required)

PHP implementation target

• lib/JIT/Context.php — remove EnvLocalRuntime::ensureLinked from ensureMinimalUserStandaloneBodies (keep ensureBootstrapAotStubLinked on bootstrap-aot path)
• Call-site: StringGetenv / JitEnv already own getenv/putenv; leave EnvLocalRuntime::ensureLinked callable for explicit use
• Unit shrink tests: stop requiring EnvLocal in minimal; add dedicated shrink test
• No new lib/AOT/runtime/*.c (floor already empty; phpc_env_local.c must stay absent)

Repro / verify

./script/aot-smoke.sh
./script/docker-exec.sh -- bash -lc 'printf "%s\n" "<?php echo \"hello\n\";" > /tmp/h.php; PHP_COMPILER_HELPER_RUNTIME_O=0 php bin/compile.php -o /tmp/h.bin /tmp/h.php && /tmp/h.bin'
./script/phpunit.sh --filter ContextMinimalStandaloneLazyEnvLocal|TypeDeadEnvLocal|EnvLocalRuntimeShrink

Done when

• Thin hello-world AOT compiles without eager EnvLocal NestedJIT in ensureMinimal
• ./script/aot-smoke.sh stays 8/8
• Unit shrink tests updated; no new lib/AOT/runtime/*.c
• bootstrap-aot stub path still ensureBootstrapAotStubLinked
