fix(dingtalk,daemon): process stream callbacks and supervise DingTalk channel

Include DingTalk in daemon supervised channel detection so the listener starts in daemon mode.

Handle CALLBACK stream frames, subscribe to bot message topic, and improve session webhook routing for private/group replies.

Add regression tests for supervised-channel detection and DingTalk payload/chat-id parsing.
