dsh-skill-recommender: DeepSeek Harness Skill Recommender

The `dsh-skill-recommender` plugin in DeepSeek Harness analyzes local session records (such as DSH, Codex, and Claude) to build a user profile, then combines local and remote skill directories and uses a weighted model to score and rank skills, recommending the best-matching open-source skills to users. It requires no API key and runs entirely locally, while allowing users to adjust weights and matching indices for filtering through a Web interface. It also provides command-line tools for scanning, generating recommendations, and checking status, with strict permissions on configuration files.
