chore: T-P-1 工作区收敛——并行会话成果与历史未入库文件整理入库

- 入库历史遗漏源码/测试：router_system 9 模块（agent/executors/inference/knowledge/
  memory/planner/skills/trace）、tests 11 个测试文件、config/knowledge 领域知识
- 入库根目录方案文档（v2/v3/可行性×2）、references 文献（arxiv 14-18/cnki_open/
  参考文献清单）、research 论文素材（routerarena/paper/中文文献 PDF）
- 前端构建产物刷新（新 hash）；webapp 误写文档删除
- gitignore 增补：deepseek-harness、research/_refs、.mimosa/.zcode、网关日志/pid、
  临时调试脚本、tests/e2e/node_modules、AI代理功能开发/prefix
- 基线确认：318 passed
