TL;DR

Moved run_command function from vite_install to a dedicated vite_command crate.

What changed?

• Removed the run_command function from vite_install/src/package_manager.rs
• Added a dependency on the vite_command crate in vite_install
• Updated all command modules to import run_command from vite_command instead
• Removed the nix dependency as it's no longer needed in vite_install
• Removed the associated tests for run_command from vite_install

How to test?

• Run the test suite to ensure all package manager commands still work correctly
• Verify that commands like add, remove, update, etc. still function properly
• Check that the command execution behavior remains consistent across platforms

Why make this change?

This refactoring improves code organization by moving the command execution functionality to a dedicated crate. This makes the code more modular and allows the command execution logic to be reused across different parts of the project without duplicating code. The run_command function is a general utility that deserves its own crate rather than being embedded in the package manager implementation.
