chore: add Makefile

[medcl]

This pull request introduces several new targets and checks to the Makefile to streamline the development and build process for a desktop application. The most important changes include setting a minimum Node.js version requirement, adding targets for installing dependencies, starting development, and building the application, and creating a clean rebuild process.

Makefile enhancements:

• Added a variable NODE_VERSION_MIN to specify the minimum required Node.js version.
• Introduced a check-node-version target to ensure the Node.js version meets the minimum requirement before proceeding.
• Added install-dependencies target to install necessary dependencies using pnpm.
• Created start-dev, build-mac-app, and build-mac-dmg targets to handle starting development and building the application for MacOS.
• Implemented a clean-rebuild target to remove node_modules and rebuild the project from scratch.
