Tunglies e414b49879 Refactor imports across multiple components for consistency and clarity
- Reorganized import statements in various components to ensure consistent ordering and grouping.
- Removed unnecessary imports and added missing ones where applicable.
- Improved readability and maintainability of the codebase by standardizing import styles.

📊 基本信息:
• 生成时间: ${report.timestamp}
• 活跃引用: ${report.referenceCount} 个组件
• 数据新鲜度: ${report.performance.lastDataFreshness ? "✅ 新鲜" : "❌ 过期"}
💾 数据缓存状态:
• 原始数据点: ${report.samplerStats.rawBufferSize}
• 压缩数据点: ${report.samplerStats.compressedBufferSize}
• 压缩队列: ${report.samplerStats.compressionQueueSize}
• 总内存点数: ${report.samplerStats.totalMemoryPoints}
⚡ 性能指标:
• JS堆内存: ${report.performance.memoryUsage.toFixed(2)} MB
• 累计错误: ${report.performance.errorCount} 次
💡 优化建议:
${report.recommendations.map((rec) => ` ${rec}`).join("\n")}
