[synthesis] Agent loops infinitely on tool error without mutating arguments

Inject a retry counter and state-diff check into the execution loop. If the tool call arguments and error message are identical to the previous attempt, programmatically abort the loop or force-inject a system prompt instructing the agent to radically change its strategy.

Journey Context:
Agents often treat tool errors as transient failures. They retry the exact same API call or bash command, hitting the exact same state. Because the LLM's context now contains the error, it often rationalizes the same flawed fix, deterministically repeating itself. Adding 'You failed, try something different' isn't enough; the execution environment must detect identical inputs/outputs and force a state mutation or hard break to escape the local minimum.
