/**
 * IndexingPipeline v2 — 索引管线
 * scan → chunk (AST / section / fixed) → detect incremental changes (sourceHash) → batch embed → batch upsert
 *
 * v2 变更:
 * - 集成 BatchEmbedder: 批量 embed 替代串行 per-chunk embed, ~50× 加速
 * - 集成 Chunker v2: auto 策略自动选择 AST / section / fixed 分块
 * - 新增 onProgress 回调支持
 * - 新增 chunking 配置透传 (strategy, maxChunkTokens, overlapTokens, useAST)
