Exclude /bibles/ and /scripts/ folders from Next.js builds

Major performance optimization:
- Completely exclude /bibles/ (7GB+) and /scripts/ directories from webpack processing
- Add watchOptions to ignore these directories during development
- Install ignore-loader to skip large data files
- Update .nextignore with comprehensive exclusion patterns
- This should reduce build memory usage from 15GB to ~2-4GB
