新增: 批次工作落地(推进链/评估闭环/事件总线/并发/加固) + 技术债清理 + 文档整理

后端:
- 工作流推进链(D-03):advance_task/状态机/闸门走 df-nodes Node trait,conditions 条件引擎扩展
- 想法评估闭环:启发式评分+对抗评估,df-ideas/scoring + df-storage/idea_eval_repo + idea 前端打通
- 全局事件数据总线:df-ai/context+context_helpers+augmentation 跨模块解耦
- AI planner/plan_hint/intent:aichat B 路线并行多轮基础
- patch_file 加固(TD-03/04):读改写整体锁防 lost update,expected_hash 合约闭环
- 压缩超时兜底(F-15 卡死根治)
- F-09 多会话并发:LlmConcurrency per-conv + streamingGuard 前端守护 + verify 脚本
- 知识注入 DRY/skills/audit 扩展

清理:
- aichat 技术债(误报 allow/死导入/过时注释 30 项)
- URGENT.md 删除(11 项加急全解决/迁 todo)
- 文档整理(todo/待决策/待审查/ARCHITECTURE/INDEX + 总线/技术债审查新文档)
