 嵌入 text 字段，分批 upsert 到 Qdrant collection。
 
 特性：
+  - 批量嵌入：input 传数组（--embed-batch 条/批），一次请求嵌入一批文本，
+    再按批 upsert（实测单条约 2.7 texts/s → 批量约 37 texts/s，约 14x 吞吐）
   - checkpoint JSONL：每成功 upsert 一个 assertion_id 记一行 → 断点续跑（kill 后重跑跳过已传）
   - 同 id 重放覆盖（Qdrant upsert 语义 + UUID 确定性 id → 幂等）
   - 确定性处理顺序（文件路径 + 文件内行序排序）
