chore: remove unused imports in layout.tsx and Hero.tsx (#676)

[kumar-ayan]

Description

Removed unused imports that were cluttering code and could cause lint failures:

• src/app/layout.tsx
  • removed import BackgroundMesh from '@/components/layout/BackgroundMesh'; (the only reference was a commented-out JSX line)
  • removed import PageTrackerInit from '@/components/PageTrackerInit'; (unused)
• src/components/home/Hero.tsx
  • removed import Image from 'next/image'; (unused)
  • removed import { MagneticText } from '../ui/magnetic-text'; (unused)

These changes keep the codebase clean and align with linting best practices.

Fixes #676

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?

• Ran project linting to confirm no unused-import warnings/errors remain for the modified files:

  • npm run lint

• Built the project locally to ensure no build-time errors introduced by removing the imports:

  • npm run build

• Verified the app starts without issues in local dev mode (spot-checked the affected pages/components)

• Local testing

• Vercel Preview Deployment

The CI failure isn't from my changes—this PR only removes unused imports from 2 files (+1 -6 lines). The 306 ESLint errors are pre-existing issues in other files (ShareButton.tsx, AuthContext.tsx, useBookmarks.ts, useGamification.ts, useMaintenance.ts, github.ts, three.d.ts). Happy to help fix those in a follow-up PR if needed!
