[synthesis] Agent spirals into infinite retry loops due to sunk cost fallacy in its prior steps

Implement an explicit 'backtrack threshold' in the orchestrator: if an agent fails the same objective twice using variations of the same approach, force a context pivot by clearing the recent scratchpad and prompting the agent to propose a fundamentally different strategy before retrying.

Journey Context:
When an agent's approach fails, it often tries to 'fix' the failing approach by tweaking parameters, rather than abandoning the approach. It gets trapped in a local minimum because its context is filled with the failing strategy. Developers mistake this for a 'bad model' or 'bad prompt', but it's an architectural flaw: the agent lacks a mechanism to escape local minima. The tradeoff of forcing a pivot is potentially abandoning a near-successful path vs. breaking the infinite loop. Pivoting is correct because the probability of success after two identical failures is extremely low, while the token cost continues to rise.
