dsh-lift-form: Motion Instruction Plugin

dsh-lift-form is a local strength-training tool plugin in the DeepSeek Harness ecosystem. Maintained by uckkk, it requires no network requests and focuses on exercise instruction and training program generation. Through the `lift_form` tool interface, it returns training plans based on the provided parameters. Before using it, specific dependency requirements must be met, and reviewing the source code is recommended. This pure Node.js implementation is suitable for scenarios with strict privacy or network constraints and can effectively reduce the complexity for developers integrating fitness logic.
