dsh-jj — Jujutsu Version Control MCP stdio Server

The DeepSeek Harness (DSH) plugin exposes the local Jujutsu (jj) version-control tool as MCP tools, aiming to provide agents with version-control operations that better align with jj semantics. The plugin has no external dependencies and supports operations such as checking status, managing changes, comparing diffs, and remote synchronization through `mcp__jj__*` tools. After installation, the Web service must be restarted. If the environment PATH configuration is special (for example, launchd), it must be overridden with an absolute path in the configuration. The plugin enhances security by using parameterized calls to prevent command injection.
