Bug Description

When receiving messages from multiple channels (Telegram, Feishu, Weibo), replies are sent to the wrong channel instead of the channel where the message originated.

Steps to Reproduce

1. Configure multiple channels (e.g., Telegram, Feishu, Weibo) with active sessions
2. Send a message from one channel (e.g., Feishu)
3. The reply is sent to a different channel (e.g., Telegram) instead of Feishu

Expected Behavior

Replies should be sent to the same channel where the message came from.

Actual Behavior

Replies are sent to the lastChannel (the most recently active session) rather than the message origin channel.

Root Cause Analysis

From the session store:

• agent:main:telegram:direct:1086468464 has lastChannel: telegram
• agent:main:feishu:direct:ou_xxx has lastChannel: feishu

When a Feishu message arrives and is dispatched to the correct feishu session, the reply still goes to the channel with the most recent lastChannel (Telegram).

Logs
