Testing: ServeAotTest — static assets from docroot with AOT binary

[PurHur]

Problem

test/real/ServeTest.php already verifies static style.css from a VM docroot (#150). test/real/ServeAotTest.php only hits the compiled PHP binary (/example.php?name=Dev) and never requests a non-.php asset.

examples/001-SimpleWeb/example.php links <link rel="stylesheet" href="/style.css">. Regressions in bin/serve-aot.php static-file handling would not fail CI.

Goal

Extend ServeAotTest (or sibling test) to:

1. Build AOT binary for examples/001-SimpleWeb/example.php
2. phpc serve --aot (or bin/serve-aot.php) docroot
3. GET /style.css → 200, Content-Type: text/css, body contains expected rule

Scope

• Reuse compile helper from existing ServeAotTest
• Assert minimal byte match from examples/001-SimpleWeb/style.css
• @group llvm + @group serve
• Document in Docs: examples/README — phpc/vm/aot run matrix per example folder #262 examples run matrix when added

Acceptance criteria

make docker-build-22
docker run --rm -v "$(pwd):/compiler" -w /compiler php-compiler:22.04-dev \
  ./script/ci-local.sh --filter ServeAotTest

passes with serve tests enabled (no PHP_COMPILER_SKIP_SERVE_TESTS).

Dependencies

• DevEx: phpc serve --aot runs precompiled CGI binary per project #213 ✅ phpc serve --aot
• Testing: Close #244 when ExampleWebAotTest matches RuntimeSuperglobalRefreshTest #260 runtime GET refresh (orthogonal; static path does not need QUERY_STRING)
