/*
 * 文件定位：Agent 执行引擎 / 执行核心逻辑 / 事件暴露面 / 基础工具调用事件。
 * 核心目的：承载 search Invocation 这一能力位点。
 * 能力要求1：需要把文件名表达的能力落实成清晰的类型、输入输出和最小行为。
 * 能力要求2：如果后续发现语义不足，应优先补接口契约，而不是把逻辑散落到相邻文件。
 * 边界：只服务 agentCore 内核，不写上层产品逻辑。
 * 对接：需要被 runtime.execEngine 拉起，并和 mainLoop、stateEngine、事件暴露、工具调用策略接通。
 * 实现提示：先补稳定类型契约、最小可测行为和清晰错误边界，再接入真实执行逻辑。
