AOT: PHPUnit dual QUERY_STRING on one compiled binary (no recompile)

[PurHur]

Problem

test/aot/ExampleWebAotTest.php compiles examples/001-SimpleWeb/example.php with -q name=Example and runs once. #49 tracks full runtime superglobal population; we lack a regression test that proves the same AOT binary honors different QUERY_STRING values without re-running bin/compile.php.

lib/AOT/runtime/superglobals_refresh.c and phpc serve --aot suggest partial runtime refresh; this issue makes the behavior testable and blocks closing #49.

Goal

One compiled binary, two invocations, two different HTML bodies:

QUERY_STRING='name=Alice' ./simpleweb | grep 'Hello Alice'
QUERY_STRING='name=Bob'   ./simpleweb | grep 'Hello Bob'

Scope

• Extend ExampleWebAotTest (or new RuntimeSuperglobalsAotTest case) to compile without -q when runtime path is ready
• Run binary twice with different QUERY_STRING / env; assert distinct output
• Document failure mode when superglobals are still compile-time baked
• Wire into @group llvm (Docker: php-compiler:22.04-dev with /opt/llvm9)

Acceptance criteria

• Test passes on master when runtime refresh is correct
• Test fails clearly (skip or fail message) when only compile-time -q works — until Web: Runtime-populated superglobals for JIT and AOT (per-request $_GET/$_POST) #49 lands

Verification (local only)

make docker-build-22
docker run --rm -v "$(pwd):/compiler" -w /compiler php-compiler:22.04-dev \
  vendor/bin/phpunit --group llvm --filter ExampleWebAotTest

Progress (batch 10)

test/aot/RuntimeSuperglobalRefreshTest::testTwoRequestsDifferentQueryString already covers dual QUERY_STRING on one binary for examples/001-SimpleWeb (#201 ✅).

Remaining scope moved to #260 (align ExampleWebAotTest) and #257 (dual REQUEST_BODY POST). Close #244 when #260 lands.
