fix(wechat): wechat_push 工具漏挂企业微信 + 提取 active_channels 单一真相源 + bump 0.26.9

根因:wechat_push_available() 只看 clawbot_enabled(),没算企业微信。线上若只开
企微渠道(ClawBot 开关没开)→ 工具压根不注册到 agent → zcbot 照实回"没有直接
发企业微信的工具",用户已绑企微仍推不出。底层 send_to_user 早支持 push_wecom,
纯属注册门槛漏判。

修:提取 service.active_channels() 作渠道清单唯一真相源,门槛(wechat_push_available)
与投递(send_to_user)都引它,加渠道只改一处,根除"两处各列各的"这类偏差。
工具描述把 ~24h 窗口注明为 ClawBot-only(企业微信无窗口约束)。

纯内部重构,对外契约不变;test_secret_host_tools 8/8 过。

 ## 已完成关键能力
 
+### 2026-06-25 / 修复 wechat_push 工具漏挂企业微信(只配企微也能推,bump 0.26.9)
+
+- bug:`wechat_push_available()` 只返回 `service.clawbot_enabled()`,完全没算企业微信。线上若只开了企业微信渠道(ClawBot 开关没开)→ 工具压根没注册到 agent → zcbot 照实回"我没有直接发企业微信的工具"(用户已绑企微仍推不出)。底层 `send_to_user` 其实早支持 `push_wecom`,门槛漏判而已。
+- 修:提取 `service.active_channels()` 作渠道清单**唯一真相源** —— `wechat_push_available()` 改成 `bool(active_channels())`、`send_to_user()` 改成 `for ch in active_channels(): _DISPATCH[ch](...)`,门槛与投递同源,加渠道只改一处,根除"两处各列各的"这类漏判。工具描述把「~24h 窗口」注明为 ClawBot-only(企业微信无窗口约束),避免 agent 在企微场景误判窗口限制。纯内部重构,对外契约不变;`test_secret_host_tools` 8/8 过。
+- 文件:`tools/wechat_bot.py`、`core/wechat/service.py`。
+
 ### 2026-06-25 / 企业微信加「手填 userid」绑定(无域名也能推,bump 0.26.3)
 
 - 痛点:企业微信只有 OAuth 扫码绑定那一路,而 OAuth 回调要落在 HTTPS 可信域名;用户暂无域名 → 卡住。关键认知:**企业微信推送是出站调用(gettoken/message_send 直连 qyapi),根本不需要域名**——只有"扫码拿 userid"那步要域名。
