dsh-rp-composer: DSH Web RP Structured Input Plugin

dsh-rp-composer is a roleplay input enhancement plugin for the Web interface of DeepSeek Harness (DSH). It addresses the issue of AI misidentifying mixed input by providing three independent fill-in fields for dialogue, actions, and inner thoughts. The plugin supports view switching, collapsible panels, and two-line sending, and can automatically assemble structured content into a standard format. It is non-invasive and compatible with other plugins, with the goal of reducing the risk of AI misjudgment and improving the roleplay experience.
