DeepSeek Harness Plugin: dsh-path-anonymizer

`dsh-path-anonymizer` is a DeepSeek Harness (DSH) plugin designed to prevent privacy leaks caused by sensitive or non-workspace paths in user messages. It uses regular expressions to detect and anonymize external paths, supports automatic replacement or a user-confirmation mode, and allows workspace paths to be retained. Users can configure exclusion rules, and the plugin takes effect after installation and restarting the Web Profile.
