fix(#715): Fix smoke workflow JSON parse and add pytest gate

- JSON: file-by-file loop with per-file error reporting
- YAML: file-by-file loop matching JSON approach
- Pytest: removed || true so it actually fails on test failure
- Deduplicated pyyaml install (single pip install step)
- Added per-step PASS messages for clear CI output
