dsh-continual-harness: Providing Continuous Refinement and Rollback for DSH Agents

`dsh-continual-harness` is a DeepSeek Harness (DSH) plugin published by `jasen215`, designed to help AI agents continuously update, retain, and refine reusable experiences across multiple sessions. The plugin is licensed under MIT, requires Node 22+ and TypeScript 6.0+, and its core features include state projection, automatic review and refinement, manual refinement with rollback, memory lifecycle management (such as archiving and pinning), and ranking injection. It provides tools such as `harness_refine`, `harness_wrapup`, and `harness_benchmark`, supporting automatic rollback on failure, session wrap-up suggestions, and A/B benchmarking to ensure that bad states do not linger in the context.
