SandboxIntegrationTests.test_glob_with_directories contradicts documented glob() files-only contract
The standard sandbox integration test in langchain-tests expects glob() to return directories (with is_dir=True), but the deepagents BackendProtocol.glob() documentation and all implementations (FilesystemBackend and BaseSandbox) explicitly return only regular files. This causes the test to fail for every sandbox backend implementation.
