feat: Add Makefile for common project tasks and pre-push checks

[joaquinbejar]

• Introduced a Makefile to streamline common tasks in the Rust project.
• Included targets for building, testing, formatting, linting, cleaning, and running the project.
• Added a pre-push target that runs critical checks before pushing code to the repository:
  • Executes cargo test to ensure all tests pass.
  • Runs cargo +nightly fmt --all to format the code and avoid formatting issues.
  • Uses cargo clippy to lint the code and enforce code quality standards.

This Makefile enhances the development workflow by providing a single interface for essential tasks, ensuring code quality and consistency before code is pushed to the repository.

We already have GitHub Actions for this, so there's no need for a makefile.
