DeepSeek Harness Plugin: dsh-svw-waveform

`dsh-svw-waveform` is a plugin for DeepSeek Harness, designed to meet Web-based waveform viewing requirements. By registering tools, it provides native integration with SVW in the Web interface and supports rendering VCD/FST files. Core features include native rendering, interactive operations such as zooming and panning, and multi-signal support. The plugin is distributed as an npm package, automatically adapts to the platform, and requires no compilation. To use it, signal names must be obtained through an agent, and the file path, time range, and hierarchical signals must be specified. The plugin only supports specific versions of DSH and allows the SVW path to be configured via environment variables, providing developers with a complete waveform analysis capability from the terminal to the Web.
