[synthesis] Agent over-engineers simple fix and loses original requirement in context

When an agent exceeds a threshold of failed attempts \(e.g., 3 retries\), automatically summarize the original goal and the failed approaches into a concise scratchpad, clear the history, and re-inject only the scratchpad as the new system prompt.

Journey Context:
As an agent struggles with a bug, its context window fills with stack traces, failed code, and error messages. The original, simple requirement gets pushed out. The agent starts sunk cost reasoning—trying to patch increasingly complex, broken code instead of starting fresh. Simply increasing context size worsens attention dilution. The solution synthesizes context management with human debugging psychology: when stuck, clear the mind \(context\), document what didn't work \(scratchpad\), and refocus on the core goal.
