[Bug]: Pi question dialog remains stuck after restarting the provider session #33519

Before submitting#

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area#

apps/desktop

Steps to reproduce#

1. Use a Pi agent in T3 Code until the agent opens a user-question menu through ask_user_question.
2. Leave the question unanswered.
3. Press Cmd+K and restart the Pi session.
4. Return to the original thread and try to continue.

Expected behavior#

Restarting the Pi session leaves the thread usable. T3 Code either cancels the old question or restores a working way to answer or dismiss it. A question belonging to a missing provider session must not permanently block the thread.

Actual behavior#

• The question dialog remains open after the session restart.
• Answer submissions fail because the original provider session does not exist.
• Stopping the thread does not clear the saved pending question.
• Settling the thread fails because T3 Code still considers it to be waiting for an answer.

Impact#

Blocks work completely
