clawhubadapter: agent 全量管理 OpenClaw 插件与通道（管理接口补齐）

新工具（agent 可直接调用）：
- plugin_info：插件详情（OC/sidecar/SKILL 类型、工具列表、关联通道及状态）
- plugin_reload：重新加载插件（reloadPlugin）
- channel_list：全部注册通道 + 实时运行状态
- channel_send：向通道注入消息（SendToChannel → channel/send → pollQueues）
- channel_start / channel_stop：通道账号启停

manager 新 RPC：
- plugins/channels：registeredChannels 摘要（type/status/accounts）
- channel/start：fire-and-forget startChannels 恢复账号（startAccount 永久挂起语义）
- channel/stop：stopAccount 停止心跳/轮询，支持按 channel 全停或按 accountId 单停

Go 侧 channelSummary 合并 manager 注册信息与 channel_status 实时缓存（缓存优先）。
验证：微信端到端（本地 mock LLM 源）channel_list 返回 wechat running=true connected=true、
channel_send 投递成功；standalone manager 验证 channel/start 心跳恢复与 channel/stop。
