Pull request overview

Adds an end-to-end usage example for Quorum\DotNotation\DotNotationParser and wires it into the generated README workflow so users can see both the code and expected output.

Changes:

• Added an “Example” section to the README including sample code and its output.
• Added a runnable example script under example/example.php.
• Updated .mddoc.xml.dist to include the example source and execute it when generating README.md.
• Added a PHP-focused .editorconfig to standardize basic editor behavior (tabs, LF, final newline).
