dsh-gomoku: Playing Gomoku with AI in DSH

omdsh-dev/dsh-gomoku is the Gomoku plugin for DeepSeek Harness, offering a 15×15 unrestricted board in the sidebar with support for human vs. AI and AI vs. AI matches. Both black and white players can independently select models, set thinking levels, and edit system prompts, with their thought processes displayed on either side of the board. Closing the popup does not interrupt the game, and invalid moves are rejected by the server. The installation command is `dsh plugin --profile demo add @yejiming/dsh-gomoku`, requiring dsh ≥ 0.1.0-rc.6.
