MasterZ9286/dsh-plugin-followup: Selected Text Follow-up and Right Panel Management

dsh-plugin-followup is a DeepSeek Harness plugin designed to solve the problems of disrupting the reading flow and cluttering the main conversation when asking follow-up details in long conversations. It allows users to select text in an answer and right-click to ask a follow-up, consolidating the Q&A content, citations, and input box into a card thread in the right-side panel, separate from the main conversation. Features include per-session independence, tab-style switching, full-text mirroring of answers, non-intrusive preservation of the reading position, and Markdown rendering support. The plugin hides follow-up turns at the rendering layer, ensuring the model context remains complete, making it suitable for code review or in-depth long-text processing.
