[synthesis] Agent loops on the same tool call or thought without throwing an error

Implement stateful deduplication by hashing the last N tool calls and their arguments. If a duplicate is detected, inject a system prompt forcing a different strategy or abort the step.

Journey Context:
Agents often get stuck in a local minimum where the LLM keeps generating the same thought/tool call because the context window still contains the same problem. Simply setting a max\_steps limit doesn't prevent the wasted steps; it just delays failure. Deduplication breaks the cycle early and forces the agent to reconsider its approach rather than burning through the context window.
