DSH Plugin: dsh-energy-plan (Energy Management)

The `dsh-energy-plan` plugin for DeepSeek Harness is an energy management tool implemented in pure Node.js. It requires no network dependencies and helps agents perform local resource assessment and planning. The plugin relies on DeepSeek-specific libraries, can be enabled through an installation command, and is used by invoking the `energy_plan` tool within a DSH session. It is suitable for scenarios with constrained network requirements or where external APIs should be avoided. Before running it, ensure that the installation source is trusted.
