/**
 * KnowledgeSyncService — 将 .md 文件增量同步到 SQLite DB（knowledge_entries 表）
 *
 * 统一替代 SyncService (Recipe) + CandidateSyncService。
 *
 * 设计原则：
 *  - .md 文件 = 完整唯一数据源（Source of Truth），DB = 索引缓存
 *  - 通过 contentHash 检测手写/手改 .md → 进入违规统计（audit_logs）
 *  - 孤儿 Entry（DB 有但 .md 不存在）→ 自动标记 deprecated
 *  - 同时扫描 AutoSnippet/candidates/ 和 AutoSnippet/recipes/ 两个目录
 *
 * 使用方式：
 *  - CLI: `asd sync` 委托调用
 *  - 内部: SetupService.stepDatabase() 委托调用（skipViolations = true）
