dsh-client-ui-writing: DSH Client Writing Panel

`dsh-client-ui-writing` is a Web client plugin within the DeepSeek Harness ecosystem, version 0.6.2, licensed under the MIT License. Designed specifically for writing preset sessions, it provides a sidebar panel and a full-book index view within the session. Its core responsibilities are reading data, displaying information, and triggering orchestration, without directly generating the main text. The plugin comprises four main functional modules: the Project tab for viewing the table of contents, statistics, and initializing projects; the Library tab for displaying imported novel information; the Search tab supporting combined full-text search across projects and libraries; and the Evolution tab for presenting setting and character evolution version chains and graphs. Furthermore, users can trigger actions such as `novel_sync` for chapter-end synchronization, summary generation, and plot twist reminders. Within the session, it supports jumping to chapters via numbers and quickly focusing the search box using shortcuts.
