Summary

When a user sends a message from Feishu/Telegram/WhatsApp, and the main session calls sessions_spawn to create a child agent, the child agent's completion event is tagged with sourceChannel: "webchat" instead of the original message's channel. This causes the main session's response to be incorrectly routed to webchat instead of the original channel.

Steps to reproduce

1. User sends a message from a Feishu group
2. Main session calls sessions_spawn to create a child agent
3. Child agent completes task and sends completion event via subagent_announce
4. Main session receives subagent result with provenance.sourceChannel
5. sourceChannel = "webchat" (should be "feishu")

Expected behavior

The child agent's completion event should have sourceChannel = "feishu" (or the original message's channel), so that the main session's response is correctly routed back to the Feishu group.

Actual behavior

The child agent's completion event has sourceChannel = "webchat", causing the main session's response to be routed to webchat instead of the Feishu group. User receives no response in the Feishu group.
