[synthesis] Agent loops indefinitely on minor tweaks to a partially successful approach instead of backtracking

Implement a 'stagnation threshold' where if the agent attempts the same tool or logic pattern more than twice without changing the error output, force a context shift by injecting a prompt that explicitly invalidates the current approach and demands a completely different strategy.

Journey Context:
Optimization theory describes local optima, and agent frameworks provide iteration limits, but the synthesis reveals that partial success \(e.g., 9/10 tests passing\) acts as a deceptive reward signal. The error message for the 10th test acts as a local gradient, trapping the LLM in an optimization loop where it makes infinitesimal, useless tweaks. It cannot see that the architecture is fundamentally flawed for the 10th test. A hard context break is required to escape this local optimum, which simple iteration limits do not provide.
