钻带解析顺序与格式优化，界面信息增强

本次更新聚焦于钻带文件解析顺序与格式的准确还原，提升了界面基础信息展示，并优化了相关数据结构和辅助方法。主要包括：
- 钻带孔位逐行顺序解析，完整保留原始坐标字符串格式，避免顺序错乱和格式丢失。
- 界面新增基础信息分组，自动统计并展示最小钻咀、槽刀、EA刀直径。
- 数据结构如Point2D等增加运算符重载和构造函数，便于几何计算。
- 机台码（0.499刀具）坐标行顺序提取及正则健壮性提升。
- 移除强制编码指定，提升跨平台兼容性。
- 清理冗余测试代码，更新示例/测试钻带文件内容。
- 新增《必读.md》，明确AI开发不需编写测试单元。
本次无其他功能或逻辑变动的占位diff。
