dsh-pet-shura: Display DSH thread status on a desktop pet

dsh-pet-shura is an MIT-licensed web-based desktop pet plugin for DeepSeek Harness (DSH), maintained by brittanistrehlowll-oss. It intuitively visualizes busy threads and the tools they call through SSE event bubbles, a thread overview refreshed every 15 seconds, and a plugin ring, addressing the issue of scattered log information. Core features include rich animations based on v2 spritesheets (e.g., walking, jumping), 16-directional mouse following, random actions, and status symbols (thinking, error, waiting, etc.). Users can double-click the pet or right-click to open a thread status card to view detailed information and adjust size, behavior, and position via the settings panel. The plugin has zero dependencies, is designed not to interfere with model traffic, stores data only in browser localStorage, and automatically removes itself upon failure to avoid disturbing the host page. Installation requires running `dsh`.
