[synthesis] Agent loops on the same failed approach because the initial flawed reasoning remains in the context window

When a retry fails, explicitly inject a system message invalidating the previous chain of thought, and force the agent to start reasoning from a different axiom or tool.

Journey Context:
When an agent fails, the failed code and the reasoning that produced it remain in context. The LLM's attention mechanism heavily weights this recent, detailed \(but flawed\) reasoning, causing it to produce syntactic variations of the exact same mistake. Simply saying 'try again' doesn't work. Developers try increasing temperature, which just adds noise. The synthesis is that the context itself is poisoned. The fix requires actively clearing the palate by summarizing the failure as a dead-end constraint and shifting the context window focus.
