将多处基于浮点的数值计算替换为 BC Math 字符串运算以避免浮点精度问题，涉及支付、退款、转账、比较与统计逻辑的重构。主要改动包括： - 将比较与判断替换为 bccomp，累加与合并使用 bcadd，乘以 100 等使用 bcmul； - 将部分初始数值与统计结果从数值类型改为字符串形式（如 '0.00'），并调整相关返回类型（如 Payment::paidAmount 改为返回 string）； - 修正订单/退款金额计算与超额校验逻辑以使用高精度算术； - 更新微信支付相关 SDK 调用中金额乘 100 的计算以避免精度误差； - 在若干插件中用高精度运算替换 floatval/int 转换（包括 SystemQueue、Wemall、Wuma 等）； - 更新文档（readme）添加 BC Math/高精度计算等说明并统一版权年份至 2014-2026； - 新增 .copilot-commit-message-instructions.md（提交信息规范）。 此改动旨在增强金融/金额相关业务的计算正确性与一致性，避免因浮点运算导致的金额误差。
