dsh-quick-invoke: A Unified `/` Command Shortcut Entry Point for DSH Web

`dsh-quick-invoke` is a standalone Cordis plugin for DSH Web, designed to simplify the invocation workflow for Skills, Agent switching, and plugin information. It provides a unified `/` shortcut entry point, allowing users to initiate invocations by selecting candidates, and automatically restores focus to the input box. The plugin is split into Host and Client components, processes operations through the official API seam, and does not modify the DSH core. Installation requires a Node.js environment and must be enabled in the Web profile. When using it, note that Agent switching requires a blank session, and plugin enable/disable commands are not supported.
