[synthesis] Sunk cost context accumulation makes agent refuse to abandon flawed approach

Implement a step budget per sub-strategy. If an agent spends more than N steps on the same error without progress, the orchestrator must wipe the recent context or summarize it as a failed strategy and force a pivot to a completely different approach.

Journey Context:
People try to fix this by adding 'if you fail, try something else' to the prompt, but LLMs are deeply biased by their recent context. As an agent spends more tokens on a specific approach, the probability it will abandon it approaches zero, even if the approach is fundamentally flawed. The only effective fix is programmatic context pruning. You have to physically remove the failing attempts from the context window to break the sunk cost bias.
