Install Vercel Web Analytics

Implemented Vercel Web Analytics for this static HTML project.

## What was implemented:

### 1. Installed @vercel/analytics package
- Added `@vercel/analytics` version ^2.0.1 to the project dependencies
- Used npm to install the package as specified in package.json

### 2. Added Web Analytics script to public/index.html
- Fetched the latest installation instructions from https://vercel.com/docs/analytics/quickstart
- Identified this as a vanilla HTML/JavaScript static site (not using any framework)
- Added the appropriate analytics script tags according to Vercel's documentation for HTML sites:
  - Added initialization script: `window.va = window.va || function () { (window.vaq = window.vaq || []).push(arguments); };`
  - Added deferred script tag: `<script defer src="/_vercel/insights/script.js"></script>`
- Placed the analytics scripts at the end of the body tag, right after the existing Speed Insights scripts

### 3. Updated dependencies and lock files
- package.json now includes @vercel/analytics in dependencies
- package-lock.json was automatically updated by npm install
- Both files are staged for the pull request

## Implementation choices:

- **Framework detection**: Examined the project structure and confirmed it's a static HTML site with no build framework
- **Script placement**: Added Web Analytics scripts at the end of the body tag to avoid blocking page load, following the same pattern as the existing Speed Insights implementation
- **Documentation source**: Used official Vercel documentation (fetched fresh from https://vercel.com/docs/analytics/quickstart) to ensure the most up-to-date installation method
- **Vanilla HTML approach**: Used the HTML/JavaScript implementation method as specified in the docs for static sites

## Testing:

- Verified build script runs successfully (static site, no compilation needed)
- Verified lint script runs successfully (no linting configured, but script executes)
- Confirmed package.json and package-lock.json were properly updated with the new dependency
- Verified the HTML structure remains valid with the new script tags

## Next steps:

After this PR is merged and deployed to Vercel:
1. Enable Web Analytics in the Vercel dashboard by navigating to the Analytics section and clicking the Enable button
2. Verify analytics are working by checking browser Network tab for `/_vercel/insights/view` requests
3. Monitor the analytics dashboard to see visitor data

The project already had Speed Insights configured, and Web Analytics has been added following the same pattern for consistency.
