feat: add Plausible analytics tracking for code overlay interactions

Add Plausible Analytics Event Tracking for Homepage Code Interactions

This PR adds analytics event tracking for user interactions with the code overlay component on the homepage:

• Added a global Plausible function definition in the site configuration to enable custom event tracking
• Implemented tracking for three specific user interactions:
  • When users click the "Reveal Code" button (home:reveal-code event)
  • When users manually scroll through the code (home:code-scroll event, tracked only once per session)
  • Added logic to distinguish between programmatic scrolling (auto-scroll or scroll-to-top) and manual user scrolling
• Added TypeScript declaration for the Plausible global function

These analytics will help us better understand how users engage with the code examples on our homepage.
