dsh-jj-vcs: Jujutsu Version Control Plugin for DeepSeek Harness

The DeepSeek Harness (DSH) plugin `dsh-jj-vcs` addresses version-control bottlenecks in multi-agent collaboration by introducing the Jujutsu version control system. It provides each agent with an isolated workspace and leverages a change-based model to deliver clear attribution auditing, concurrency safety, and operation tracing. Its core features include creating independent changes, explicit permission tiers, controlled publishing, and Windows compatibility. Developers must install it manually and depend on JJ 0.44.0, using the coordinator script to start tasks and verify changes, thereby providing a robust version-management solution at the community level for enterprise-grade multi-agent projects.
