Optimize Agent Prompt

Optimize a Browserbase Agent's systemPrompt while holding its task, result schema, variables, and evaluation criteria fixed. Treat the outer agent as the teacher and each Browserbase Agent run as an inner-agent rollout.

Use Node.js 18 or later and set BROWSERBASE_API_KEY. The harness uses only Node.js built-in modules.
