[synthesis] Agent continues down a failing approach refusing to backtrack despite repeated failures

Implement a 'sunk cost detector' that counts consecutive tool failures. Upon hitting the threshold, truncate the recent failing history, explicitly instruct the agent that the previous approach failed, and prompt it to propose a completely different strategy.

Journey Context:
Agents exhibit a form of sunk cost fallacy. If an agent spends 5 steps trying to install a specific library and fails, it will try increasingly bizarre variations of the install command rather than switching to a different library or approach. The context window is filled with the 'history' of this approach, biasing the model to continue it. Simply telling the agent 'try again' doesn't work because the failing context is still there. Truncating the failing history and explicitly resetting the approach forces the agent out of the local minima, treating the context window as a recoverable asset rather than an immutable ledger.
