dsh-web-icon-indicator: Browser Tab Status Indicator

`dsh-web-icon-indicator` is a browser extension for DeepSeek Harness (DSH) that modifies tab icons in real time to reflect session status (idle, running, asking, completed). It supports multiple dynamic visual effects, displays the number of active agents, and features background protection and self-healing mechanisms. Users can customize colors, effects, and display duration through a built-in interface. This tool translates background process states into clear visual signals, making it suitable for multi-agent collaboration scenarios.
