Add Prettier Configuration for Consistent Code Formatting #6

Description

Implement Prettier as the code formatter to ensure consistent code style across the project. This will help maintain code quality and improve developer experience.

Current State

• No standardized code formatting
• Potential inconsistencies in code style across files
• Manual formatting required

Proposed Changes

1. Add Prettier and related dependencies:

   • prettier
   • prettier-plugin-tailwindcss
   • eslint-config-prettier
   • eslint-plugin-prettier

2. Create configuration files:

   • .prettierrc with modern formatting rules
   • .prettierignore for excluded files
   • .vscode/settings.json for editor integration

3. Add npm scripts:

   • format: Format all files
   • format:check: Check if files need formatting

4. Update ESLint configuration to work with Prettier
