Introduction to the Fullstack Expert Plugin

`adithya-hmt/fullstack-expert` is a full-stack engineering plugin designed specifically for the DeepSeek Harness (DSH) coding agent, addressing pain points such as missing execution workflows, unconstrained operations, and insufficient evidence. By defining key operation nodes such as `fullstack_plan` and `fullstack_check`, it provides a complete closed loop spanning repository inspection, vertical slice planning, sensitive operation approval, and verification evidence logging. It emphasizes evidence-driven engineering standards based on the Cordis framework, reuses host capabilities, and is suitable for full-stack development scenarios requiring strict auditing and security.
