dispatcher 不再手搓 pool.Stream,改用编译好的 Eino 图驱动;接入用户常驻画像,
推理前召回并注入 system prompt,实现个性化(架构'心脏'首次真跳)。
Eino 图(dispatcher/internal/eino): START→recall→prompt→model→END + 全局 State
- recall(Lambda): 取 Meta[user_id] → 调 MCP memory_get → ProcessState 写画像
- prompt(ChatTemplate): {profile} 注入 system,{query} 作 user
- model: poolModel 适配 LLM Pool 为 model.BaseChatModel(Generate+Stream, schema.Pipe)
- 写回: 流排空后异步 memorize(流式节点走 OnEndWithStreamOutput 非 OnEndFn)
记忆存储(mcp-go owns): GORM Profile→sundynix_user_profile(复合主键, AutoMigrate,
遵守前缀约定), 新工具 memory_get/memory_upsert, 连不上降级
Gateway: SubmitTask 注入 Meta[user_id](X-User-ID 头), PUT /api/v1/memory→memory_upsert
shared: contract.MetaUserID; llm.Pool 拆出 StreamText
验证: 4 模块 build✓ + 3 e2e PASS; live 跑通——PUT 偏好落 sundynix_user_profile,
带 X-User-ID 提交→Eino recall 召回→注入→SSE 流出含画像的个性化回答, writeback 触发
