Feat/add husky (#223)

# Add Husky and lint-staged for automated code quality checks

## Description
This PR adds Husky Git hooks and lint-staged to automate code quality
checks during the development workflow.

## Features Added
- Pre-commit hook that runs lint-staged to check files before committing
- Pre-push hook that runs tests and type checking before pushing
- Configuration for lint-staged to format and lint different file types
- Documentation explaining the Husky setup and usage
- Updated README.md with information about Git hooks

## Benefits
- Ensures consistent code style across the project
- Prevents pushing code with failing tests or type errors
- Reduces the need for style-related code review comments
- Improves overall code quality

## Implementation Details
- Added Husky and lint-staged as dev dependencies
- Created pre-commit and pre-push hooks
- Added configuration for lint-staged
- Added documentation in HUSKY.md
- Updated README.md with a new section on Git hooks

## Testing
The hooks have been tested locally and work as expected:
- Pre-commit hook runs ESLint and Prettier on staged files
- Pre-push hook runs tests and type checking
