dsh-heat-level: Return Home-Style Cooking Plans Based on Parameters

The DeepSeek Harness plugin `dsh-heat-level` is designed to address the challenge of determining the appropriate heat level in cooking scenarios. Implemented in pure Node.js with no network dependencies, it allows developers to obtain specific home-cooking instruction plans by providing input parameters. To install it, use the `dsh plugin add` command. Once enabled, the `heat_level` tool can be invoked within DSH sessions. When using the plugin, developers should pay attention to dependency versions and potential security risks, and it is recommended to review the source code before installation.
