[synthesis] Agent runtimes increase and quality drops without explicit failure states

Set a hard limit on the mutation radius of tool call arguments during retries. If an agent retries the same tool more than twice with only minor parameter tweaks, halt the run and log a local minimum error rather than allowing it to brute-force a degraded success.

Journey Context:
When an agent encounters an API error, it retries with slightly modified parameters. This looks like normal self-correction. However, when the agent is flapping, it is stuck in a local minimum. It might eventually get a 200 OK by passing a trivial parameter, but the resulting state is semantically useless \(e.g., creating an empty file instead of the requested module\). Monitoring sees a successful, albeit slow, completion. The leading indicator is the variance of the arguments in consecutive retries—if variance is low, it is flapping, not self-correcting.
