Switch to Bun runtime for faster performance

Updated the entire project to use Bun instead of npm/yarn for:
- Faster package installation (3x faster than npm)
- Native TypeScript support
- Better runtime performance
- Built-in bundler

Changes:
- Updated package.json to use bun in all scripts
- Renamed project from example-marketing to localgreenchain
- Added bunfig.toml for bun configuration
- Updated README with Bun installation instructions
- Added "Why Bun?" section explaining benefits
- Updated .gitignore for bun-specific debug logs
- Changed all npm/yarn references to bun commands

All commands now use:
- bun install (instead of npm install)
- bun run dev (instead of npm run dev)
- bun test (instead of npm test)
