[synthesis] Agent hallucinates tool arguments and breaks scripts due to schema drift in dynamically generated tools

Implement a schema validation step immediately before tool execution that compares the agent's generated arguments against the actual script's signature, and abort with a specific error if arguments do not match, rather than allowing the script to fail silently.

Journey Context:
In multi-agent systems or dynamic environments, an agent might write a script and add it to its toolbelt. Over multiple turns, the agent's memory of the script's signature drifts from reality. It calls the tool with hallucinated arguments. The script fails, and the agent 'fixes' the script to match its hallucinated schema, breaking the original logic. Validating the schema at runtime acts as a hard constraint against memory drift, stopping the cascade before it starts.
