[synthesis] Agent parameter drifts into invalid state during iterative tool calls

Implement a parameter diff check against the original intended state before every tool call retry, ensuring the agent's changes are monotonic towards the goal and not random walks.

Journey Context:
When an agent fails to invoke a tool correctly, it often adopts a trial-and-error approach, tweaking parameters one by one based on error messages. This random walk can lead to a state where multiple parameters are wrong simultaneously. Developers rely on the LLM to figure it out, but LLMs lack an internal map of the valid parameter space. The fix requires external validation of the parameter state, treating retries as a directed search rather than a generative guess, applying directed search constraints to LLM self-refinement loops.
