DeepSeek Harness (DSH) Plugin: dsh-bookmark — Codex-Style Conversation Navigation

dsh-bookmark is a client-side plugin for DeepSeek Harness designed to address the inefficiency of manually scrolling through long conversations to locate prompts. The plugin adds compact navigation markers to the conversation sidebar, supporting hover previews, click-to-jump navigation, and keyboard shortcut navigation. It runs entirely locally in the browser, without reading API keys or sending data to external servers. Users need to install it using the specified command and restart the Web process after installation for it to take effect.
