[OPTIMIZE] 文件路由机制，新启动 LOGO，护眼文档

[MT-SUPER-POWER]

PR 摘要 (Summary)

加入了文件路由机制，规则如下：

譬如说 module 和 api 的关系如下
ni_hao.js 则对应接口 --> /ni/hao

引入文件路由机制之后：

文件夹路径是这样子的：/hello/momo/ni_hao.js --> 请求就是：/hello/momo/ni/hao
如果是这样子的：(hello)/(momo)/ni_hao.hs --> 请求就是: /ni/hao
于是使用 (文件夹) 来分类并不会破坏接口，同时分类的文件。如果有其他开发做新的接口，就可以自己起一个文件夹，譬如说 /v1 这样就可以和原接口分离，方便二开

加入了新的启动 LOGO

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

此拉取请求旨在通过引入模块化的文件路由机制来优化项目结构，这使得接口管理更加灵活，并为未来的功能扩展奠定了基础。同时，为了提升用户体验，更新了应用程序的启动标志，并为文档页面添加了护眼模式。这些改进共同提升了项目的可维护性、用户界面和开发效率。

Highlights

• 文件路由机制: 引入了新的文件路由机制，通过使用 (文件夹) 命名约定来组织模块，从而在不破坏现有接口的情况下实现更好的分类和扩展性。例如，/hello/momo/ni_hao.js 对应的请求路径是 /hello/momo/ni/hao，而 (hello)/(momo)/ni_hao.hs 对应的请求路径是 /ni/hao。
• 新启动 LOGO: 更新了应用程序的启动 LOGO，提供了全新的视觉体验。
• 护眼文档: 为文档页面引入了暗色模式，旨在提供更舒适的阅读体验，减少眼睛疲劳。
• 许可证更新: 更新了项目许可证信息，增加了新的版权声明。

Code Review

这个 PR 主要进行了一次大规模的文件结构重构，引入了基于文件和目录的路由机制。大部分模块文件被移动到了按功能组织的带括号的目录中，例如 (album)、(artist) 等，这种方式在不影响现有 API 路由的情况下改善了项目的可维护性。同时，所有被移动文件的内部 require 路径也都相应地被更新了。此外，PR 还新增了一个用于获取默认搜索关键词的接口 search_default。本次审查没有发现严重程度为 medium 或更高的代码问题。代码变更主要是结构性的，并且遵循了 PR 描述中提到的新路由规则。
