/**
 * GAIA Agent — ADR-133-PR3 / ADR-135 (planning interval)
 *
 * Multi-turn Anthropic Messages API loop that drives Claude through the
 * GAIA benchmark questions using a tool-use agent pattern.
 *
 * Loop algorithm:
 *   1. Build initial message with the question and a system prompt that
 *      instructs Claude to output `FINAL_ANSWER: <value>` when done.
 *   2. Call Anthropic Messages API with the registered tool definitions.
 *   3. On `stop_reason === 'tool_use'`: execute all tool_use blocks in
 *      parallel, append results as a `user` turn, and repeat.
 *      Every PLANNING_INTERVAL turns, inject a planning-checkpoint text
 *
