dsh-plugin-optimization: DSH Plugin Partition Manager

`dsh-plugin-optimization` is a DSH plugin management component maintained by AJUbest, licensed under the MIT License. It aims to address the confusion caused by scattered DSH plugin sources and optimize extensibility through a "everything is a plugin" approach. The component divides the plugin list into two independent partitions: "built-in plugins" and "custom plugins," and consolidates custom plugins into the `~/.dsh/custom-plugins/` directory. Its core functions include browsing plugin directories, importing plugins from Git URLs, local paths, or npm packages, automatic registration, enabling/disabling and deleting plugins, and automatically migrating legacy plugins to designated partitions. Additionally, it provides reminders for missing dependencies and plugin conflicts. Users need to ensure that Node.js and p... are installed on the local machine.
