DeepSeek Harness Plugin: dsh-better-command

`dsh-better-command` is a DeepSeek Harness (DSH) plugin maintained by Lovstudio that aims to address the inflexibility of `/` menu command and skill matching. Through runtime replacement, it provides an intelligent matching service that is separator-transparent and abbreviation-aware. It supports quick location of hyphen-separated commands via abbreviations (such as `dshp`) and includes multi-level filtering with full re-ranking. Installation requires Node.js 22.19+, computation runs entirely in the browser, and uninstalling restores the default behavior.
