dsh-load-estimate: Electric Load Estimation

DeepSeek Harness (DSH) provides a `dsh-load-estimate` plugin for accurately calculating the power consumption of model inference locally. Maintained by uckkk, it uses a pure Node.js implementation and requires no network dependencies. After installation, it can be invoked through the `load_estimate` tool, making it suitable for local resource planning. Note that it runs with the permissions of the current process, so it is recommended to review the source code before installation.
