/**
 * LoopContext — reactLoop 单次执行的完整状态

 * 封装原 reactLoop 内散落的 10+ 局部变量:
 *   - 注入依赖 (messages, tracker, trace, memoryCoordinator, sharedState)
 *   - 循环状态 (iteration, lastReply, toolCalls, tokenUsage)
 *   - 错误恢复 (consecutiveAiErrors, consecutiveEmptyResponses)
 *   - 配置 (source, budget, capabilities, baseSystemPrompt, toolSchemas, prompt)
 *
 * 使 reactLoop 的提取方法只需接收一个 ctx 参数。
