docs: add interactive documentation system with Go+HTMX

- Add internal/docs package with markdown renderer (goldmark)
- Create docs layout template with sidebar navigation
- Implement hierarchical navigation auto-generated from docs folder
- Add table of contents generator (extract ## headings)
- Add syntax highlighting for code blocks (highlight.js)
- Add mobile responsive design
- Add /docs routes to main.go

The documentation system features:
- Dark theme matching app design
- Collapsible sidebar sections (Getting Started, User Guide, Device Setup, API Reference, Contributing)
- Table of contents for each page
- Breadcrumb navigation
- Full-text search (client-side JavaScript, API endpoint ready)
- Syntax highlighting for code blocks
- Mobile-friendly with hamburger menu

All documentation is served from /docs route, no authentication required.
Markdown files are rendered using goldmark with GFM extensions and syntax highlighting.
