feat(agent): 触发后处理可配置(运行模式/合并模式/并发上限) + 修复抽屉内下拉误关

每个自定义 agent 可配置触发后如何调度运行:
- 运行模式 serial|parallel:串行排队一次一个 / 每次触发各自并发一个会话
- 合并模式 by_task|all|none(仅 serial):同任务合并 / 全部合并成一条 / 不合并
- parallel 带每 agent 最大并发上限(0=不限),超限排队等空位

实现:
- DB: agents 加 trigger_run_mode/trigger_merge_mode/trigger_max_parallel 三列
  (schema + 幂等 ALTER 迁移,已发版补旧库);Agent 结构/scan/SetAgentTriggerBehavior
- 调度重构: triggerRun bool → triggerActive 计数 + triggerCfg 缓存;
  StartTriggeredRun 走 pumpLocked/runAndPump 统一泵模型,nextTriggerRun 按合并模式
  取(新增 mergeAllRuns);并发安全(session 按 conv-id 隔离,已确认)
- config 接口暴露/接收三字段;max_turns 改可选指针,避免触发 tab 部分 patch 清零
- 前端: 触发 tab 顶部加运行/合并模式下拉 + 最大并发输入,改动即存

修复: 抽屉(Sheet)内 Select 下拉 portal 到抽屉外,点选项/点别处被当成点击外部
误关抽屉。SelectContent 改 position=popper,并给 SheetContent 加 onInteractOutside
守卫(按 e.detail.originalEvent.target 判定弹层内点击则不关)。
