DeepSeek Harness (DSH) Plugin: dsh-base62 Base62 Encoding Tool

The `dsh-base62` plugin for DSH (DeepSeek Harness), maintained by uckkk, is a pure Node.js-based Base62 encoding tool with no network dependencies. It enables agent development to convert data locally into Base62 strings. The installation command is `dsh plugin add github:uckkk/dsh-base62`, and it depends on `@deepseek-ai/cordis` and `@deepseek-ai/dsh-tools` at runtime. Since the plugin runs with the permissions of the current DSH process, review the source code and license before installation.
