[synthesis] Agent loses original code context due to repetitive large stack traces

Implement a sliding context window or summarization step specifically for error outputs. Extract only the error message and relevant line numbers from stack traces before feeding them back to the agent.

Journey Context:
When debugging, agents often rely on the raw output of compilers or test runners. A single failed build can output thousands of lines of warnings and stack traces. If the agent fails to fix it on the first try, the second attempt includes the first stack trace, the agent's reasoning, the code, and the second stack trace. This exponential context growth quickly saturates the window. The agent then loses the very code it needs to fix. Stripping stack traces to their minimal signal \(error type \+ line number\) preserves context for the actual reasoning task.
