dsh-kpa2psi: kPa to PSI Converter Tool

dsh-kpa2psi is a DeepSeek Harness plugin maintained by uckkk, designed to address pressure unit conversion needs. It is implemented in pure Node.js, supports converting kilopascals to PSI, and does not require internet access. The installation command is `dsh plugin add github:uckkk/dsh-kpa2psi`. Before using it, ensure that the environment meets the dependency requirements for `@deepseek-ai/cordis` (^4.0.1) and `@deepseek-ai/dsh-tools` (>=0.1.0-rc.6). Since the plugin runs with DSH process privileges, it is recommended to review the source code and license before installing.
