Add professional wiki documentation

[Copilot]

The project lacked structured reference documentation beyond a single README, making it hard for new users, contributors, and operators to find targeted information.

Added wiki/ directory with 9 pages

• Home.md — Entry point: quick-start table, feature highlights, tech stack, page index
• Installation.md — All deployment paths: Docker one-liner, Docker Compose, bare static server, desktop binary
• Usage-Guide.md — Editor, import/export, view modes, sync scroll, share-via-URL, keyboard shortcuts
• Features.md — Per-feature deep-dives: syntax highlighting, LaTeX/MathJax, Mermaid diagrams, privacy/XSS model
• Markdown-Reference.md — Full CommonMark + GFM syntax reference; includes LaTeX and Mermaid examples
• Desktop-App.md — Neutralinojs architecture, dev setup, all three build modes, CI release flow, per-platform run notes
• Docker-Deployment.md — Docker run/compose, embedded Nginx config, reverse-proxy snippets (Nginx, Caddy, Traefik)
• Contributing.md — HTML/CSS/JS style guidelines, Conventional Commits reference, branch/PR workflow
• Configuration.md — Complete settings reference: localStorage keys, Docker/Nginx tunables, neutralino.config.json fields, GitHub Actions trigger matrix
• FAQ.md — 25+ Q&As covering general use, features, offline support, troubleshooting, and contribution
