feat: implement WYSIWYG markdown editor with Go backend and React frontend

Implements full markdown editor application with: Backend (Go): - Cobra CLI with --data-dir, --port, --host flags - REST API for CRUD operations on markdown files - File storage on disk with flat structure - Logrus logging for all operations - Static asset serving for frontend - Comprehensive tests for CRUD and static assets Frontend (React + TypeScript + Tailwind): - Markdown editor with live GFM preview - File management UI (list, create, open, save, delete) - Theme system (Dark, Light, System) with persistence - Responsive design (320px to 1920px) - Component tests for core functionality Integration: - Full CRUD workflow from frontend to backend - Static asset serving verified - All tests passing (backend: 2/2, frontend: 6/6) Files added: - Backend: API handler, logger, server, tests - Frontend: Components, tests, config files - Build artifacts: compiled backend binary and frontend dist - Documentation: README and implementation summary
