Reorganize documentation navigation for onboarding and component discovery

[Copilot]

Documentation navigation was not optimized for developer onboarding or component browsing. Menu hierarchy buried quick start content, and components lacked a comprehensive overview page.

Changes

Navigation Hierarchy

• Reordered top-level menu: Getting Started → Components → Concepts → Advanced → Community
• Renamed "Guide" to "Getting Started", "Reference" to "Advanced" for clarity
• Integrated Ecosystem into Advanced section

Component Gallery

• Created /docs/components/index.mdx as component discovery hub
• Lists all 40+ components organized by 8 categories (Basic, Form, Layout, Data Display, Feedback, Overlay, Disclosure, Complex)
• Includes usage patterns and schema examples

Navigation Structure

Getting Started (was 4th → now 1st)
  ├─ Quick Start (prioritized)
  ├─ Installation (prioritized)
  └─ Interactive Demos

Components (was 3rd → now 2nd)
  ├─ Component Gallery (NEW)
  ├─ Basic (Text, Icon, Image, Separator, HTML)
  ├─ Form (Button, Input, Select, Checkbox, Switch, Textarea, Slider)
  └─ ...8 categories total

Advanced (renamed from "Reference")
  ├─ API Reference
  ├─ Protocol Specification
  └─ Ecosystem

Technical Details

• All meta.json files use flat structure (Fumadocs requirement)
• Category headers in sidebar via ---CategoryName pattern
• No URL changes, all existing links preserved

UI Changes

New Navigation Structure
