dsh-context-snapshot-bar: Observing Runtime Context and Traces in DeepSeek Harness Web

`dsh-context-snapshot-bar` is a visualization plugin for DeepSeek Harness Web designed to address the lack of observability for context windows and message compression. It provides an entry point above the input box and displays hidden Session events in a visual format in the right sidebar, featuring three core capabilities: runtime snapshot nodes, context snapshot details, and a conversation trajectory view. The plugin can be installed via npm (version 0.2.0) and depends on DSH 0.1.5-rc.2 and Node.js 22+. It reads session data in read-only mode without modifying runtime strategies. With this tool, developers can intuitively inspect a model's context composition, message states, and compression status.
