Security: Example app update Next.js dependency for CVE-2025-55184 and CVE-2025-55183 (#951)

## Premise

On December 11, 2025, Next.js disclosed two security vulnerabilities
affecting applications using React Server Components with the App
Router:

1. **CVE-2025-55184 / CVE-2025-67779** (High Severity) - Denial of
Service via infinite loop
2. **CVE-2025-55183** (Medium Severity) - Source code exposure in Server
Functions

These vulnerabilities originate in the upstream React RSC protocol
implementation. While neither allows Remote Code Execution, upgrading to
patched versions is required.

## Changes

Changed `examples/next-app/package.json`:

| Package | Before | After |
|---------|--------|-------|
| `next` | 15.4.8 | 15.4.10 |
