feat(gateway): 地基③ 打通实时信号 producer→前端WS + loop 真流式 + 上行路由补全

打通前端 ws.ts 里那批死消费者事件（thinking/mood/tool_used/subagent_event/
task_output/device_update/reminder/backthink），并给 loop 接真 token 流式。

- wire.go：loop 建时传 OnStream（streamChunk 闭包把 delta 发 bus ws.stream_chunk）；
  gateway.Deps 注入 Scheduler/Tasks/Streaming；iot 接共享总线 iot.WithBus(a.bus)。
- ws_bridge.go：hub 额外订阅 iot.>/task.>/automation.>/reminder.>/cyrene.agent.*.event，
  normalizeEvent 归一为 ws.*（device_update/task_output/task_done/automation_result/
  reminder/subagent_event）；不订阅 cyrene.agent.> 以免 ask/reply 内部事件进 relay。
- ws_route.go：voice_input→ws.voice_input；subagent_ask→Scheduler.AuditContext（真实
  上下文审计，替换 pending stub）；task_output_query→Manager.TaskOutput（真实输出，
  替换空 {}）。
- server.go：新增 SubagentAuditor/TaskOutputStore 接口 + Deps.Scheduler/Tasks/Streaming。
- orchestration/auditcontext.go：Scheduler.AuditContext(full/tail/keyword)。
- task/manager.go：Manager.TaskOutput(id)。
- backthink：record() 补发 ws.backthink 事件。
- json tag 修正（device_update/reminder/task output 结构体加小写 tag + DeviceUpdate
  补 message），使前端分支能真正渲染。

实机验证：WS 握手 101、task manager ready、iot manager initialized(WithBus 生效)。
go build/vet/test 全绿；TestHubBridgeDeviceUpdate/TestHubBridgeSubagentProgress 覆盖
映射。dev 推至后续版本。
