feat: 支持 acp-link 包进行 acp 通用的 remote-control (#292)

* fix: 修复超时问题

* feat: 添加 acp-link 代码

* refactor: 样式重构完成

* feat: RCS 添加 ACP 后端支持

- 新增 ACP WebSocket handler (agent 注册、EventBus 订阅)
- 新增 relay handler (前端 WS → acp-link 透传 + EventBus inbound 转发)
- 新增 SSE event stream 供外部消费者订阅 channel group 事件
- ACP REST 接口无鉴权 (agents、channel-groups)
- WebSocket 端点保留 token 鉴权
- SPA 路由 /acp/ 指向 acp.html
