Re-enable YAML parse error test in config_test.go

- Renamed test to "should return helpful error for malformed YAML"
- Changed logic: test now expects error (was incorrectly expecting success)
- Verifies error message includes file path and line number
- Temporarily updated CI to run only config tests for verification
