omdsh-shortcuts: Binding Key Chords to DeepSeek Harness

omdsh-shortcuts is a plugin-based input tool for DeepSeek Harness, designed to address the difficulty of uniformly managing keyboard shortcuts across desktop and web interfaces. It allows key chords to be defined in a single document while monitoring key presses in both native desktop menus and web pages, and provides a visual configuration interface. The plugin offers low-level API services, supporting multiple UI commands and window management. Installation requires Node.js ^22.19.0 or >=24.0.0. Note that certain browser-side shortcuts (such as Cmd+N) are reserved and must not be overridden, otherwise plugin mounting will fail.
