feat(waiter): daemon模式 + localuse本机外设插件

Browse Source 
waiter 新增 --daemon 后台驻留模式 (daemon.go):
  - 维持 homed 连接，TUI实例经 Unix socket 接入
  - 单客户端串行模型：每个TUI独占homed响应，新客户端回放缓冲(256行)
  - 设备桥场景可无 homed 运行（纯设备桥驻留）
  - 设备桥看护循环：WS断开自动重连(3-5s间隔)
  - conn.go 新增 daemonConn 类型，dial() 优先检测 daemon

localuse 插件 (internal/plugins/localuse/):
  - local_screensee / local_camerasue / local_speakeruse
  - local_screensue / local_clipboardsee / local_clipboardsue / local_computeruse
  - 跨平台实现(Linux/macOS/Windows)，能力与 waiter device.go 对齐
  - headless服务器上缺依赖工具自动返回安装提示

SDK sync: third_party SetToolBlocks 多模态类型同步

### 后台驻留模式（daemon）
waiter 也支持后台驻留，保持与 homed 的持久连接并等待 TUI 实例接入，适合让 agent 主动召唤用户/设备桥持续存活：
```bash
# 后台驻留（默认连 ~/.homeagent/cli.sock）
./build/waiter --daemon
# 指定 socket
./build/waiter --socket /path/to/cli.sock --daemon
# 随后任意 TUI/一行实例都会自动接入正在运行的 daemon，而不是直连 homed
./build/waiter
```
daemon 监听 `~/.homeagent/waiter.sock`，新客户端连入时会回放缓冲的最近对话（256 行），断连后 daemon 持续存活、自动重连 homed，并保持设备桥（若配置了 `device_gateway`/`device_token`）。
API 密钥通过 WebUI `http://localhost:8080` 设置页配置，持久化在 SQLite 中。
