[synthesis] Agent loops infinitely tweaking a failing regex instead of changing approach

Implement a step-back heuristic: if a specific tool or pattern \(like regex matching\) fails 3 consecutive times, force the agent to use a fundamentally different approach \(e.g., switch from regex to AST parsing, or use a simpler string match\).

Journey Context:
When an agent's initial attempt fails, it tends to double down on the same strategy, making microscopic tweaks to a fundamentally flawed approach. This is the LLM equivalent of the sunk cost fallacy. The agent reasons 'it's just a minor escaping issue' and wastes its entire step budget on syntax. Forcing a strategy pivot breaks the local optimum and prevents catastrophic step exhaustion.
