- similarasin/appearancepatent 模块全部 Coze 工作流调用改走 direct-LLM（已确认唯一运行路径）
- 共享组件改名：CozeTaskQueueGate→TaskQueueGate、CozeGroupResultPropagator→GroupResultPropagator
- 状态机改名：biz_task_scope_state 的 coze_* 列→llm_*、stateJson coze 键→llm（V100 迁移已应用生产）
- 删除 biz_coze_credential 表、CozeCredential* 类、SimilarAsinCozeClient、AppearancePatentCozeClient→LlmClient
- 前端 brand 页 Coze 文案→LLM；Python 后端删除 cozepy 依赖与死配置
- 修复 TaskResultFileJobWorker 启动失败：TaskFileJobConfig 注册 ResultFileJobHandlerRegistry 与 13 个 handler bean（含 validateCoverage 启动校验）
