feat: implement WYSIWYG markdown editor
Add full-stack markdown editor with Go backend and React frontend. Backend: - Cobra CLI with --data-dir, --port, --host flags - REST API for markdown file CRUD operations - File storage with flat directory structure - logrus logging for all operations - Static file serving for frontend - Comprehensive tests for CRUD and static assets Frontend: - React + TypeScript + Vite + Tailwind CSS - Live markdown preview with marked (GFM) - File management: list, create, open, save, delete - Theme system: Dark/Light/System with persistence - Responsive design (320px to 1920px) - Component tests for Editor, Preview, Sidebar Build: - Makefile for build, test, and run automation - Single command testing (make test) Closes SPEC.md requirements
