API Timeout Recovery Failure: Unexpected Tool Result Error After 'Successful' Subagent Execution

Bug Description
Claude hit a ton of API timeout errors and then a subagent 'succeeded' with zero tokens and Claude appeared to recover and produced valid output but at the end of its turn I got the dreaded tool_result error. I'll have to either go back to before the timed out message and hope it works OR start a new chat because this branch of the conversation is corrupted.
