fix(provenance): populate entries alias in get_lineage and read lineage_chain in lineage()

- Add entries alias in get_lineage() return dictionary so CLI and programmatic callers can access lineage entries via either key

- Update lineage() wrapper method to fallback to lineage_chain when entries is missing

- Add assertions in test_cli_lineage confirming lineage and entries lists are non-empty
