stubs/InMemoryAdapter.php:24

• PR metadata says this doesn't break BC, but Yiisoft\\Queue\\Stubs\\StubAdapter is removed and InMemoryAdapter becomes the replacement stub implementation. Since stubs/ is shipped via Composer autoload (Yiisoft\\Queue\\Stubs\\), removing/renaming these classes is a public API change. Consider keeping StubAdapter as a deprecated alias or updating the PR's BC declaration/release notes accordingly.
