- 将原本分散在 `parse_diff_side_by_side` 与 `parse_pipe_diff_table` 的两套解析逻辑合并，新增统一的 `parse_one_diff_line` 工具函数 - `parse_one_diff_line` 同时识别 `|a|b`、`a | b`、`a<b` / `a>b` 等多种 diff 输出格式，便于后续扩展 - 简化 `parse_diff_blocks` 中 full mode / simple mode 的内联解析流程，消除代码重复 - 优化 `raw_error` 换行符归一化处理，兼容 `\r\n` 与单独 `\r` 结尾的情况
