feat: Add Prettier configuration and format check workflow

- Introduced .prettierrc for consistent code formatting with specified rules.
- Added .prettierignore to exclude unnecessary files from formatting.
- Updated package.json to include Prettier and lint-staged as devDependencies.
- Implemented GitHub Actions workflow for format checking on pull requests and pushes.
- Created a Husky pre-commit hook to run lint-staged for automatic formatting.

These changes enhance code quality and maintainability by enforcing consistent formatting across the codebase.
