feat: AirPlan V2 — 全专家插件强制路由 + 事件系统规范化

P0-8 扩大: do_mode.py finish_worker 全专家插件强制路由
- GUI→XDB, network→NDB, C/C++→SDB, done→Rvr, blocked/failed→Dbg
- 证据去重: 已有 xdbSessions/ndbSessions/sdbReports/rvrReviewed 则跳过

P1-GAP17: 事件 emit 规范化
- 新增 7 个事件常量 (TASK_ENTERED, TASK_FINISHED, ENGINE_ENTERED 等)
- 全部 emit 调用替换字符串字面量为常量，零残留
- 30 个事件类型常量全部定义且唯一

P1-GAP18: 事件日志原子轮转
- emit 计数器每 128 次检查轮转，避免每次 emit 读文件
- 清除未使用的 _emit_with_completion/_pending_merge_complete
- 原子轮转: tempfile+os.replace 保证不损坏

eng 极端接管: 强制调用全部专家插件 (Dbg/XDB/NDB/SDB/Rvr)
commands/do.md: 更新为全专家插件路由文档

全量测试: 69 通过, 0 失败
