Report #71368

[synthesis] Agent claims task is complete but actually hit context window limit

Explicitly check the API response finish\_reason for length instead of relying on the agent's text output, and implement automatic context summarization or handoff.

Journey Context:
When an agent runs out of tokens, the API truncates the output. If the agent was in the middle of a JSON tool call or a final summary, the truncated output might still be valid JSON or text that looks like a successful completion, or the LLM just stops mid-thought and the framework interprets the lack of tool call as 'done'. Developers trust the framework's parser. The fix requires treating finish\_reason=length as a hard error that triggers a context compression routine, not a stop condition.
