dsh-keyboard-manager: DeepSeek Harness Web UI Keyboard Shortcuts

dsh-keyboard-manager is a plugin for the DeepSeek Harness Web UI designed to reduce mouse interactions through keyboard shortcuts. It provides the following shortcuts: Ctrl+Q (toggle the sidebar), Ctrl+E (intelligently switch between the right-side panel or detail page), and Ctrl+S (settings/save). The plugin is released under the MIT license, supports customizing key bindings via configuration files, and does not interfere with native events. It depends on Cordis ^4.0.2 and is compatible with the dsh-better-sidebar plugin.
