📚 Add VitePress Documentation

Description

Add VitePress as the documentation framework to provide comprehensive, searchable documentation for the vue-custom-tooltip library.

Motivation

• Current README.md is limited for detailed documentation
• Need interactive examples and API reference besides the current github page
• Better developer experience with searchable docs
• Showcase component features and usage patterns with code snippets

Proposed Implementation

1. Install VitePress as dev dependency
2. Set up documentation structure:
   • Getting Started guide
   • Installation instructions
   • Component API reference
   • Directive usage guide
   • Configuration options
   • Accessibility features
   • Interactive examples/playground
   • Performance benchmarks
3. Configure build scripts in package.json:
   • docs:dev - local development server
   • docs:build - production build
   • docs:preview - preview built docs
4. Deploy documentation to GitHub Pages or Vercel
