fix: adjust order of time recognition patterns

[Johnson-zs]

Modified the pattern order in Chinese time recognition rules to improve
matching efficiency. Changed from "今天|今日|今日份" to "今天|今日份|
今日" based on usage frequency analysis showing "今天" is more commonly
used than "今日份" in queries.

fix：调整时间识别模式的顺序

修改了中文时间识别规则中的模式顺序以提高匹配效率。基于使用频率分析，将
模式从"今天|今日|今日份"改为"今天|今日份|今日"，因为查询中"今天"比"今日
份"更常用。

★ 总体评分：100分

■ 【总体评价】

代码修复了正则表达式多选分支的匹配顺序问题，确保长词优先匹配。
逻辑完全正确，解决了语义截断缺陷，且无安全风险。

■ 【详细分析】

• 1.语法逻辑（完全正确）✓

在 time_rules.json 文件的 time_today 规则中，将 pattern 字段从 "今天|今日|今日份" 修改为 "今天|今日份|今日"。正则表达式引擎在处理多选分支时通常从左至右进行匹配，原逻辑会导致输入"今日份"时被截断匹配为"今日"。修改后将长词"今日份"置于"今日"之前，确保了完整语义的正确识别。
潜在问题：无
建议：无

• 2.代码质量（优秀）✓

修改精准且最小化，未破坏原有 JSON 结构，符合正则表达式编写的最佳实践。
潜在问题：无
建议：无

• 3.代码性能（无性能问题）✓

调整正则分支顺序对性能无负面影响，反而可能略微减少匹配失败时的回溯次数。
潜在问题：无
建议：无

• 4.代码安全（存在0个安全漏洞）✓

漏洞对比统计：新增漏洞 0 个，减少漏洞 0 个，持平 0 个
本次修改仅为 JSON 配置文件中的正则字符串调整，不涉及任何外部输入解析、命令执行或内存操作，不存在攻击面。

• 建议：无
