[synthesis] Context window fills with failed attempts, causing agent to lose sight of original goal

Implement a 'context compression' step: once the error history exceeds a certain token threshold, summarize the failed attempts into a single 'what not to do' bullet point and reset the context window with the original goal plus the summary.

Journey Context:
As agents fail and self-correct, the context window fills with stack traces and broken code. The LLM starts suffering from attention dilution, focusing on the recent errors rather than the original objective. Simply appending more context makes the agent myopic. Summarizing the failures and resetting the context restores focus on the primary goal.
