fix: update Chinese filetype matching patterns

[Johnson-zs]

Added "包" to the Chinese filetype matching pattern for applications to
improve search accuracy. The existing patterns ("安装包|软件|应用|脚本|
程序") were missing some common variations of application-related terms
in Chinese user queries.

Log: Improved Chinese application file type detection in search

Influence:

1. Test search functionality with term "包" for application files
2. Verify existing search patterns still work correctly
3. Check if false positives are introduced for non-application files
4. Ensure all application-related search terms return appropriate
   results

fix: 更新中文文件类型匹配模式

在中文应用程序文件类型的匹配模式中增加了"包"字，以提高搜索准确性。原有的
匹配模式("安装包|软件|应用|脚本|程序")缺少了对中文用户查询中应用程序相关
术语的某些常见变体。

Log: 改进了搜索中中文应用文件类型的检测

Influence:

1. 使用"包"字测试应用程序文件的搜索功能
2. 验证原有搜索模式是否仍然正常工作
3. 检查是否会对非应用程序文件产生误判
4. 确保所有应用程序相关的搜索词都能返回适当结果

Fixes: #370655

★ 总体评分：100分

■ 【总体评价】

代码修改了文件类型识别的正则表达式规则，逻辑正确且符合规范
仅新增一个匹配词，无性能损耗与安全漏洞，评分满分

■ 【详细分析】

• 1.语法逻辑（完全正确）✓

在 src/dfm-search/dfm-search-lib/semantic/rules/zh_CN/filetype_rules.json 文件的 filetype_application 规则中，正确地向 pattern 数组追加了 |包 选项，JSON 语法格式保持正确无误。
潜在问题：无
建议：无需修改

• 2.代码质量（符合规范）✓

修改方式简洁明了，直接在原有正则表达式末尾增加匹配分支，符合现有的配置风格与缩进规范。
潜在问题：匹配词 包 较为宽泛，可能会导致非应用包类型的文件被误判为应用
建议：若 包 字容易引起误匹配，建议使用更精确的词汇或在描述中明确其匹配范围

• 3.代码性能（无性能问题）✓

正则表达式中增加一个简单的字符串分支匹配，对正则引擎的匹配效率影响微乎其微，不会引发性能瓶颈。
潜在问题：无
建议：无需修改

• 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，不存在安全风险。

• 建议：无需安全修复

■ 【改进建议代码示例】

{
    "id": "filetype_application",
    "pattern": "安装包|软件|应用|脚本|程序|包",
    "description": "Application packages",
    "enabled": true,
    "priority": 150
}
