feat(phoneuse): send_wechat_image MCP 工具改走内部 API（全图 CDN 上传）

图片 CDN 上传打通后，把 MCP 发图工具从旧的 share-intent UI 模拟切到内部 API: - wechat_hook_send.py: 新增 send_image_via_hook(wxid, image_path) — 先 stage 到 /sdcard 保证 WeChat 进程可读，再广播 SEND_IMAGE_INTERNAL；hook 内部走 b80.u.oj(插库+建描述符) + v70.w.oj(提交 CDN 上传)，接收方收全分辨率原图。新增常量 SEND_IMAGE_ACTION。旧 send_image_via_intent 保留作参考/UI 兜底。 - android_mcp.py: send_wechat_image 工具改调 send_image_via_hook，更新 docstring （无 UI 模拟、无选联系人、无发错人风险；nickname 不解析，须传 wxid）。真机验证（off-device 走 wechat_hook_send.send_image_via_hook 直调）: status=sent + hook oj() DONE + CDN submit DONE items=1。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

-        Send an image to a WeChat contact via the share intent + UI tap flow.

-        Copies the image to /sdcard, fires android.intent.action.SEND into WeChat,
-        searches for the contact in the select-contact sheet, and taps 发送.
+        Fires SEND_IMAGE_INTERNAL → WeChat's own image plugin (b80.u.oj inserts the

+        original (not a stuck thumbnail). Fire-and-forget: delivery is async after
+        the broadcast; confirm via a WeChat UI screenshot if needed.
-        Verified approach (from wechat-image-sender Hermes skill, 2026-06-23).
-        Coordinates are fraction-based; reference screen 1344×2992.
