feat: 7-61 Yuxi reference — extensions panel, KB detail, manifest split, event router, dashboard

Batch B: settings popover 新增"扩展"tab，按知识库/Skills/MCP/Agent工具分面板
Batch C: knowledge-rag popover 新增"资料源管理/检索测试/检索参数"三tab
Batch A: manifest.rs 按能力域拆为 10 个分组函数（context/doc/knowledge_rag/block/page/mindmap/office/onlyoffice/artifact）
Batch D: 新增 agent-stream-event-router.js 共享模块（事件状态机 + SSE 帧解析）
Batch E: settings popover 新增"仪表盘"tab — 知识库文件数/Skills数量/MCP连接状态/Agent run次数
