feat: implement WYSIWYG markdown editor
Add complete markdown editor with Go backend and React/TypeScript frontend. Backend: - Cobra CLI with configurable host, port, data-dir, static-dir flags - REST API for CRUD operations on markdown files (GET, POST, PUT, DELETE) - File storage with flat .md structure - Comprehensive Logrus logging for all operations - Static asset serving for frontend Frontend: - React 18 + TypeScript + Tailwind CSS - Live markdown editor with GFM preview (react-markdown) - File management UI (list, create, open, save, delete) - Theme system (Light/Dark/System) with localStorage persistence - Responsive design (320px - 1920px+) Testing: - 6 backend tests covering CRUD round-trip, validation, error handling - 19 frontend tests covering API, theme system, and UI components - All tests passing with single 'make test' command Build: - Frontend compiles to optimized assets in dist/ - Backend can serve frontend via --static-dir flag
