Install Vercel Speed Insights for Next.js

## Vercel Speed Insights Implementation

Successfully installed and configured Vercel Speed Insights for this Next.js portfolio project.

### What was implemented:

1. **Installed @vercel/speed-insights package**
   - Used npm (the project's package manager) to install `@vercel/speed-insights` v1.3.1
   - Updated package.json and package-lock.json with the new dependency

2. **Added SpeedInsights component to root layout**
   - Modified `app/layout.tsx` to import SpeedInsights from '@vercel/speed-insights/next'
   - Added the `<SpeedInsights />` component inside the `<body>` tag, after the main content
   - Placement follows Next.js App Router best practices for Next.js 15.5.12

### Files Modified:
- `app/layout.tsx` - Added import and component
- `package.json` - Added @vercel/speed-insights dependency
- `package-lock.json` - Updated with new dependency tree

### Implementation Details:
- The project uses Next.js 15.5.12 with App Router, which is newer than 13.5+
- Used the simplified approach: imported from '@vercel/speed-insights/next'
- No 'use client' directive needed as the package handles this internally
- The component is placed at the end of the body tag for optimal performance

### Verification:
- Build completed successfully with `npm run build`
- No errors or warnings introduced
- All changes have been staged with git

The Speed Insights component will now automatically track Core Web Vitals and send analytics data to Vercel when deployed.
