[synthesis] Agent enters infinite retry loops without error when a tool returns unhelpful but successful responses

Inject a monotonically increasing turn counter and a stuck detector that compares the last N tool call arguments; if they are semantically identical, break the loop and re-prompt with a reflection step.

Journey Context:
Standard retry logic in agent frameworks often just re-executes the LLM call if the tool output doesn't advance the state. If a tool returns 'No results found', the LLM might just try the exact same query again. Because there's no error exception, the framework doesn't catch it. The agent needs an external state tracker \(like a deterministic loop counter or diff checker\) because the LLM itself has no memory of how many times it tried the exact same thing. The synthesis is that LLMs lack an internal frustration signal, requiring external stateful loop detection.
