Pull request overview

This PR updates the project’s JS/PHP tooling dependencies and migrates ESLint to v10’s flat config approach, aligning lint/test tooling with newer WordPress packages.

Changes:

• Bump NPM and Composer dependencies (notably @wordpress/scripts, @wordpress/eslint-plugin, PHPStan).
• Replace legacy ESLint config (.eslintrc.js / .eslintignore) with eslint.config.mjs (flat config) and update references in docs/workflows.
• Adjust TypeScript config to include Jest/Node types and update a PHPUnit compatibility shim in the PHP test base.

ReflectionClass is referenced unqualified inside the rtCamp\Plugin_Skeleton_D\Tests namespace, so PHP will try to resolve rtCamp\Plugin_Skeleton_D\Tests\ReflectionClass and this will fatal at runtime. Use the global \ReflectionClass (as before) or add use ReflectionClass; at the top of the file.

Suggested change

	$class_reflection = new ReflectionClass( static::class );
	$class_reflection = new \ReflectionClass( static::class );
