Description: Rule-driven, auditable cleaning of survey and assessment
        response data, implementing the WeianData Detect-Execute-Report
        workflow. Provides a multi-format, multi-encoding input layer
        (CSV, 'Excel', 'SPSS', 'Stata', 'SAS', Parquet, JSON), the
        dcc_data container with a provenance chain, level-0 structural
        diagnostics, five built-in response-quality detectors (missing
        items, straight-lining, response time, trap items, score
        anomalies), a declarative YAML rule engine, an execution engine
        with a cell-level audit log, answer-key scoring, multi-form to
        master item bank mapping, a normalized report model rendered as
        bilingual staff workbooks and HTML, complete statistical
        bundles, and versioned machine JSON/JSONL with
        findings-to-changes reconciliation, cell-level lineage tracing,
        and manifest-based one-command reproduction. Includes a
        protected bilingual strict project workbook and matching JSON
        contract with cell-addressed validation, non-mutating
        preflight, preview-first execution, and localized staff
        guidance. All formally supported input backends install with
        the package; PDF is optional rather than a fixed report output.
