DSH Plugin Marketplace: Managing HTTPS Plugin Repositories, Verifying Downloads, and Managing Static Plugin Plug/Unplug

This plugin is a Host plugin marketplace under the DSH philosophy, designed to address issues related to plugin source management, download verification, and enable/disable control. It provides a Web-based configuration page for managing HTTPS repositories and supports the installation, verification (SHA-256), and lifecycle management of both static and dynamic plugins. The download process is secure and atomic, ensuring that code is written only to the installation directory and is not executed automatically. Developers need to first merge core patches into the DSH mainline and then consume this repository as a dependency to use it.
