fix: correct spacing and formatting in multiple files

[Morgy93]

This pull request consists of minor code quality and consistency improvements across several files, as well as a small fix to template escaping. The most significant change is the consistent use of the $escaper object for URL escaping in the frontend template to improve security and maintain best practices.

Frontend template security and consistency:

• Updated src/view/frontend/templates/inspector.phtml to use the $escaper object instead of $block for URL escaping in both the stylesheet and script tags, ensuring proper output sanitization. [1] [2]

Code formatting and style improvements:

• Fixed formatting in several PHP files by adding proper line breaks before docblocks and after method closures in CheckCommand.php, BuildCommand.php, and the NodePackageManager constructor for better readability and adherence to coding standards. [1] [2] [3] [4]
