dsh-iron-temp: Ironing Temperature Lookup Tool

`dsh-iron-temp` is a DeepSeek Harness (DSH) plugin intended to resolve the lack of specific parameter support for agents handling clothing care. Maintained by developer uckkk, it is implemented in pure Node.js with no network dependencies. It registers the `iron_temp` tool, enabling users to get precise ironing temperature recommendations by passing parameters such as fabric type. Installation requires running `dsh plugin add github:uckkk/dsh-iron-temp` and ensuring the environment meets the requirements of `@deepseek-ai/cordis` (^4.0.1) and `@deepseek-ai/dsh-tools` (>=0.1.0-rc.6).
