/clear drops custom agent system prompt while keeping agent label in UI

[074cefd2]

Describe the bug

/clear apears to clear the active agent from behaviour but the UI isn't updated to reflect this

Affected version

GitHub Copilot CLI 1.0.39.

Steps to reproduce the behavior

1. Select a custom agent via /agent
2. Confirm agent is active — model follows agent-specific workflow instructions
3. Use /clear to start a new conversation
4. Note the UI still shows the agent name (e.g. "debug") at the bottom of the chat
5. Send a message that requires agent-specific behaviour
6. Note /agent shows the previous custom agent active also but previous behaviour suggests it was reset

Expected behavior

text and /agent menu should reflect active agent. /clear should probably set the agent and the text to default
