🛠️ Spec-kitty: Spec-Driven AI Coding Workflow

The direction here is quite interesting. Instead of just building another chat wrapper for code generation, it focuses on Spec-Driven Development. In short, it tries to formalize the AI coding workflow: you write clear specifications first, and then let models via Claude, Cursor, or Gemini execute the implementation. It includes a Kanban dashboard, Git worktree management, and auto-merge capabilities. The hard part of AI-assisted development is rarely generating a few lines of code; it is managing that code within a serious software engineering environment. This project acts more like an agile scaffolding for the AI era, helping developers track progress systematically.
