fix(lint): remove bare except, fix unused vars/params in yaml_exporter, toon_parser

- parsers/toon_parser.py: bare except → except Exception
- exporters/yaml_exporter.py: remove unused nfuncs variable;
  rename compact→_compact in export_data_flow/export_data_structures,
  fn→_fn in _create_node, edges→_edges in _render_modules
All 278 tests pass, all regix gates pass.
