feat: add package name search configuration

[wjyrich]

1. Added new DConfig setting "searchPackage" to control package name search functionality
2. Implemented package name search in SearchFilterProxyModel when enabled
3. Added DConfig monitoring to dynamically update search behavior when setting changes
4. Package name search includes exact match, starts with, and contains matching
5. Added desktopId comparison in calculateWeight method for package name matching

The changes allow users to enable/disable package name searching through DConfig, providing more flexible search options. This is particularly useful for technical users who may want to search applications by their package names.

feat: 添加包名搜索配置功能

1. 新增 DConfig 设置项 "searchPackage" 用于控制包名搜索功能
2. 在 SearchFilterProxyModel 中实现包名搜索功能（当启用时）
3. 添加 DConfig 监听以动态更新搜索行为
4. 包名搜索支持精确匹配、开头匹配和包含匹配
5. 在 calculateWeight 方法中添加 desktopId 比较用于包名匹配

这些改动允许用户通过 DConfig 启用/禁用包名搜索功能，提供更灵活的搜索选
项。对于技术用户来说特别有用，他们可能希望通过包名来搜索应用程序。

Summary by Sourcery

Enable users to search applications by package name by adding a DConfig-controlled switch and matching logic in SearchFilterProxyModel

New Features:

• Add DConfig setting searchPackage to toggle package name search
• Extend SearchFilterProxyModel to include desktopId-based matching (exact, prefix, substring) when enabled
• Monitor DConfig changes to dynamically update search behavior

Reviewer's Guide

This PR integrates a new DConfig-based toggle to enable or disable package name searching globally and extends the existing SearchFilterProxyModel to dynamically react to configuration changes and weight matches against the app’s desktopId when enabled.

Hey @wjyrich - I've reviewed your changes - here's some feedback:

• Pass this as the parent in DConfig::create to ensure the DConfig instance is properly cleaned up instead of leaking.
• Move m_dconfig and m_searchPackageEnabled into a private section in the header to avoid exposing internal state.
• Extract the desktopId search clauses out of calculateWeight into a helper method to keep the weight logic more focused.

关键摘要:

• 在searchfilterproxymodel.cpp中，m_dconfig的初始化应该放在构造函数的初始化列表中，以提高代码的可读性和性能。
• Q_ASSERT_X用于检查配置文件的有效性，这是一个好的做法，但是应该确保在所有可能的情况下都有相应的错误处理机制。
• 在calculateWeight函数中，desktopIdLower变量被创建但未在注释中说明其用途，应该添加注释来解释其作用。
• m_searchPackageEnabled变量在配置变化时被更新，但是没有检查配置值是否真的发生了变化，直接更新可能会导致不必要的性能开销。
• qDebug用于在配置变化时输出日志，这在调试阶段是合适的，但是在生产环境中应该避免使用qDebug，或者至少应该提供一种方式来启用或禁用这种日志输出。

visibility为private,表明它是私有的配置，仅当前应用设置，你这个之后可能由dde-control-center改写吧，是不是应该是public的，
