Introducing the DeepSeek Harness Plugin: dsh-plugin-oh-my-engine

`dsh-plugin-oh-my-engine` is a plugin for DeepSeek Harness (DSH) that introduces an Oh My Engine (OME) engineering delivery model with approval gating into DSH. It adds an isolated `ome-engineer` preset for Web and Desktop profiles, consumes services through OME’s public API, and supports file system operations, sandboxed shell execution, and full workflow management. The plugin provides `/ome-*` commands for initialization, state management, approval, and diagnostics. Installation does not require Git and can be completed by downloading a prebuilt package. When using it, note CLI limitations, port occupation issues, and context inheritance rules. It is suitable for scenarios requiring strict stage gates and user approval.
