🛡️ Sentinel: [CRITICAL] Remove Public Debug Endpoint Exposing Environment Variables

[GerryK97]

• 🚨 Severity: CRITICAL
• 💡 Vulnerability: A public debug endpoint (src/app/debug/route.ts) was accessible without authentication and exposed sensitive environment variables. Notably, it leaked the first 60 characters of MONGODB_URI, which in many cases exposes the username, password, and cluster details. It also exposed NEXTAUTH_URL.
• 🎯 Impact: An attacker could trivially discover the database credentials by accessing the public /debug endpoint, leading to full compromise of the application's database.
• 🔧 Fix: Completely deleted the debug endpoint file as instructed by the file's own comments ("DELETE THIS FILE BEFORE DEPLOYING TO PRODUCTION"). Also logged the finding to the .jules/sentinel.md journal.
• ✅ Verification: Verified that src/app/debug/route.ts no longer exists, ran linters, and performed a build to ensure the removal did not break any other application features.
