relay-dsh-plugin-monitor-process: Identity-safe Process Monitoring

The `relay-dsh-plugin-monitor-process` for DeepSeek Harness (DSH) is a Relay-based monitoring plugin designed to provide read-only, identity-safe process status queries. It is maintained under the MIT license, with core features including issuing process handles bound to sessions and projects, and ensuring that PIDs are received only when issued and are not embedded in the Bundle. Users must run the specified installation command to obtain a compatible version. The plugin requires no additional adaptation, but it must operate within DSH process permissions; verifying the source code before installation is recommended.
