fix(vector): 写入回执、行级模型出处与模型感知回填选择器 - #450
Conversation
写入侧：embedFor/schedule 返回结构化回执（ok/failed/skipped + 原因），
schedule 不再吞掉 promise；失败进 200 条环形账本（embedReceipts()），
不接 llm_audit_logs（高频回填会淹没 LLM 调用的追溯面）。
出处侧：memories 新增 embedding_model 列（行级 model hash）。
vector_meta.model_hash 是『最后一次成功写入的模型』，换模型即被整表
覆盖，无法回答『这一条向量是谁产的』。存量一律 NULL（出身未知），
不按时间推断模型名——猜出的名字会被日后审计当作证据，而它不是。
清空向量时连同出处一起清，NULL 向量不挂陈旧模型名。
选择器侧：新增 needsEmbeddingFor(modelHash)/hasStaleEmbedding，
捞『空向量 OR 出身未知 OR 模型不匹配』；needsEmbedding 保留原语义。
回填与 reindexMissing 走新选择器：换模型后旧向量真正被重算，
而不是永远占着『有向量』名额虚增覆盖率。embedder 未配置时回退
旧行为，不整表空跑。
上限侧：backfillMissingEmbeddings 的 maxTotal=0 语义为一灌到底；
boot 回填的 500/10/200 改为 reindexMaxPerBoot/reindexBatchSize/
reindexRateLimitMs 配置项；返回 {indexed, processed, failed,
finishReason, stillStale, ...}——capped 与 drained 不再不可区分；
createSemantic.backfillStatus() 暴露最近一次回填状态。

回填会反复选中嵌入失败的行。maxTotal=0 时循环不会结束。 失败行一直满足陈旧条件，pick(batchSize) 每一轮都会再次返回它们。如果服务端持续失败，无上限模式会一直请求服务端。有上限时，配额会被同一批失败行反复消耗。
dsh-mneme/src/semantic.js#L45-L68：记录本轮已尝试的 id 并跳过它们，或在一批全部失败时退出循环。dsh-mneme/lib/semantic.js#L45-L68：同样修改，或修改 src 后执行npm run sync。

为模型写入路径传递 modelHash。
needsEmbeddingFor() 会把 embedding_model IS NULL 的活动行判定为待处理行。service.js 的两个 embedSingle 写入路径，以及 vector-index.js 的 rebuildIndex()，都调用 setEmbedding() 时省略了 modelHash。因此，这些路径写入的向量仍可能在下一次自动回填时被再次选中，重复消耗嵌入调用。src 和 lib 版本都需要同步修改。
🐛 建议修复
-store.setEmbedding(memory.id, vec);
+store.setEmbedding(memory.id, vec, embedder.modelHash);-store.setEmbedding(row.id, vector);
+store.setEmbedding(row.id, vector, embedder.modelHash);将上述修改同步应用到 dsh-mneme/lib/service.js 和 dsh-mneme/lib/vector-index.js。

背景
本机记忆库实测：活跃记忆约 4791 条，有向量的 608 条（覆盖率 12.7%），其中能确定属于当前模型的只有今天新写的约 200 条；10-03 至 10-16 的写入全部拿不到向量，且没有任何一处会报错或上报。根因有三，互为叠加：
embedFor成功/失败都无返回值，schedule()不返回 promise 且.catch(() => {})吞掉一切——「这条写入到底有没有拿到向量」在进程内无处可查。WHERE embedding IS NULL OR embedding = ''只捞空值。vector_meta.model_hash是全库单值（最后一次成功写入的模型），换模型即被整表覆盖，上一代模型产出的向量从此永远占着「有向量」的名额，相似度却与新查询不可比——覆盖率虚高，语义召回实际残废。maxTotal=500, batchSize=10, rateLimitMs=200硬编码，开机只跑一次；4151 条缺口需要九次重启才能轮完，且被截断的运行与跑完的运行返回值完全相同。改动
A · 写入回执
embedFor返回{status: ok|failed|skipped, id, at, reason?, dim?, model?}；不再成功失败都返回 undefined。schedule()返回回执 promise（rejection 仍不抛出——向量失败绝不阻断记忆写入这条契约不变）。embedReceipts()：最近 200 条环形账本 + 累计{ok, failed, skipped}+ 最近失败原因。有意不接llm_audit_logs：一次回填数千次调用会把那张表的 LLM 追溯面淹没。C · 行级模型出处
memories新增embedding_model列（行级model#hash）。setEmbedding(id, vector, modelHash)写向量与出身同一句 UPDATE；清空向量时连同出处一起清，NULL 向量不挂陈旧模型名。清空/未带 modelHash 的调用方行为不变。选择器（C 的查询面）
needsEmbeddingFor(modelHash)：捞「空向量 OR 出身未知 OR 模型不匹配」；hasStaleEmbedding单条探测；embeddingModelBreakdown按模型分组计数（状态页可直接用）。reindexMissing走新选择器——换模型后旧向量真正被重算。embedder 未配置或 store 无新方法时自动回退旧行为。needsEmbedding原语义保留，现有调用方不受影响。B · 回填上限可配置
config.js新增reindexMaxPerBoot（0 = 不设上限一灌到底）/reindexBatchSize（1-64）/reindexRateLimitMs，默认值维持 500/10/200 行为不变。backfillMissingEmbeddings返回{indexed, processed, failed, finishReason: capped|drained|all-failed, stillStale, startedAt, finishedAt, model}——capped 与 drained 从此可区分。createSemantic.backfillStatus()暴露最近一次 boot 回填状态。测试
node --test：1875 个用例，1874 过，0 失败（基线 1867）。reindexMissing两个断言按新返回值改写；旧 store（无新方法）兼容回退有测试兜底。风险与边界
addColumn幂等）。llm_audit_logs、审计链、dream/sleep 路径均未触碰。Summary by CodeRabbit
