## React Flight / Next.js RCE Advisory Patch Implementation

### Summary
Updated the quant-arena repository to address the React Flight / Next.js RCE advisory by patching the vulnerable Next.js version.

### Vulnerability Detection
- **Next.js**: Found version 16.0.1 (vulnerable)
- **React Flight packages**: None found (react-server-dom-webpack, react-server-dom-parcel, react-server-dom-turbopack not in use)
- **Conclusion**: Project is affected via Next.js dependency only

### Changes Made

#### Modified Files
1. **package.json**
   - Upgraded `next` from 16.0.1 → 16.0.7 (applies patched version per advisory)
   - Upgraded `eslint-config-next` from 16.0.1 → 16.0.7 (matching major.minor.patch for consistency)

2. **package-lock.json**
   - Automatically updated by npm install to reflect patched dependencies
   - Verified that lockfile contains next@16.0.7

3. **bun.lock**
   - Deleted (not used by project, npm is the active package manager)

### Implementation Details

**Why these changes:**
- Next.js 16.0.7 contains the security patch for the RCE vulnerability in Next.js 16.0.x series
- React and React-dom versions (19.2.0) were NOT manually modified per advisory instructions: "For Next.js projects, do not manually upgrade react or react-dom. Next.js will supply the correct patched React dependency versions automatically."
- No React Flight packages were found in the project, so section 3 of the advisory did not apply
- eslint-config-next was updated to match the Next.js version for consistency and compatibility

### Build Verification
- ✅ `npm install` completed successfully with patched versions
- ✅ `npm run build` completed successfully
  - Prisma Client generated (v6.19.0)
  - Next.js 16.0.7 compiled successfully using Turbopack
  - All pages generated without errors
- ✅ `npm run lint` executed (pre-existing linting issues present but unrelated to this patch)
- ✅ Lockfile properly reflects patched version (next@16.0.7)

### Important Notes
- React and React-dom remain at 19.2.0 as per advisory guidelines for Next.js projects
- The project does not use any React Flight packages (react-server-dom-*)
- The vulnerability is fully mitigated by upgrading Next.js to 16.0.7
- All changes follow the advisory's upgrade rules for Next.js 16.x releases
