Subject: [PATCH] Add test for tar_dir error path

Added a new test case `test_tar_dir_error_path` to `stdlib/tests/stdlib_tests.rs`
to verify that `compress::tar_dir` correctly returns an error when passed an
invalid source path. The test safely creates a temporary directory for output
to avoid leaving uncleaned artifacts in `/tmp`.
