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

- Agent 列表按 channel group 分组，显示在线状态
- 通过 RCS WebSocket relay 与 agent 通信
- Vite multi-page 构建 (index.html + acp.html)

* feat: acp-link 支持 RCS relay 双向通信

- rcs-upstream 新增 messageHandler 转发非控制消息
- server.ts 新增虚拟 WS + relay client state 处理 relay ACP 消息
- newSession/loadSession 补充 mcpServers 参数
- 连接成功后显示 ACP Dashboard URL

* fix: 修复类型问题

* feat: RCS 后端统一 ACP/Bridge 注册逻辑

- store: EnvironmentRecord 增加 capabilities 字段、storeFindEnvironmentByMachineName 复用逻辑
- store: 新增 storeGetSessionOwners，支持未绑定 session 自动 claim
- environment: registerEnvironment 支持 ACP 复用已有记录，返回 session_id
- session: resolveOwnedWebSessionId 支持无 owner session 自动绑定
- acp-ws-handler: 新增 handleIdentify 支持 REST+WS 两步注册
- acp routes: /acp/relay 和 /acp/agents 支持 UUID 认证
- event-bus: 增加 error 类型 payload 日志

* feat: acp-link 改 REST 注册 + WS identify 两步流程

- rcs-upstream: 新增 registerViaRest() 通过 POST /v1/environments/bridge 注册
- rcs-upstream: WS 连接后发送 identify 替代 register，携带 agentId
- rcs-upstream: 入口链接改为 /code/?sid=${sessionId} 实现用户绑定
- server: 修复心跳跳过 relay 虚拟连接的 bug
- server: maxSessions 配置传入 RCS upstream

* refactor: 删除 /acp/ 独立页面，ACP 聊天统一到 /code/:sessionId

- 删除 acp.html、acp-main.tsx 入口文件和 pages/acp/ 目录
- SessionDetail: ACP session 在同一页面渲染 ACPSessionDetail 组件
- App.tsx: ?sid= 参数自动调用 apiBind 绑定用户 UUID
- Dashboard: 统一 session 列表导航，ACP 显示紫色标签
- relay-client: 改用 UUID 认证替代 API token
- EnvironmentList: 显示 workerType 标签（ACP Agent / Claude Code）
- index.ts: 移除 /acp/ SPA 路由，vite.config 移除 acp 入口
