"""三层新闻去重模块 (M3)。

公共 API:
    - Deduper:         主类（check / ingest / stats）
    - FingerprintStore: SQLite 指纹库（底层，通常无需直接用）
    - DedupResult / DedupLayer / DedupStats / Fingerprint: 数据模型
    - simhash64 / hamming / content_hash / normalize_content: 指纹算法
    - dedup_all_sources / dedup_source: 批量去重管道
