dsh-moyan: Displaying a Quote in the DeepSeek Harness WebUI Sidebar

dsh-moyan is a lightweight plugin for the DeepSeek Harness WebUI, released under the MIT license, designed to display famous quotes, classical poetry, or iconic lines with minimal interference in the sidebar, positioned above the "Settings" button. The plugin does not alter the core workflow and primarily provides a maintainable quote slot with refresh controls. Core features include: automatic line wrapping to display sentences and their sources, support for refresh frequencies of "every open" or "daily" (with automatic quote changes across midnight); manual quote switching and the ability to roll back up to the last 5 entries, while the 10 most recently displayed quotes are not repeated in random selection. The corpus is stored externally in `corpus.txt`, supporting real-time editing that takes effect without requiring a service restart. The interface automatically adapts to light/dark modes by following the Harness theme variables, and it automatically hides when the sidebar is collapsed. Installation requires Node.js ≥ 18 and pnpm.
