The failing test expects parse_config to fall back to defaults when an env var is an empty string. Locate the parser first.

Presence check is wrong; the value must also be non-empty. Same bug for RETRIES. Patch both and add a regression test.

Resolved. Empty TIMEOUT / RETRIES now use defaults; regression test added in tests/test_config.py::test_empty_env_falls_back.
