feat(channels): 适配器日志接 WS 实时推送(落库即秒推, channel_persisted)

后端: persistIsolated 由 _ = full(不广播)改为 notifyPersisted(full); BroadcastPersisted 按
sessionId 分流——main/web:<uuid> → message_persisted(Web聊天同步), 隔离 sess-xxx → channel_persisted
(适配器日志专用, 永不写主会话 web, 红线). payload data:{message:historyMessage}(strip thinking).
前端: ws.ts 新增 channel_persisted case→parseAdminChannelMessage→pushChannelEvent; wsParse.ts 纯函数;
useAppStore 新增 channelEvents(最新在前,按id去重,cap200,不持久化); channelLogList 订阅过滤
(单adapter按adapterId/总览取adapterId非空)merge进列表(仅追加、id去重、不整页重载),保留拉历史+10s兜底.
Docs/api-client.md §3.4 补 channel_persisted 契约.
验收: 后端 build/vet/test 全绿+windows/darwin交叉编译绿; 前端 npm run build 99模块绿.
注: 偏离=web:<uuid> 归 message_persisted(保Web副会话同步), 隔离永不带web前缀红线仍守.
