✅ Quality Checklist

Local Environment & Hooks

• Local Git hooks (CaptainHook) are installed and executed cleanly.
• Commit messages strictly follow the (PRE|SMP)-XXXX: description pattern.
• Core configuration files (phpstan.neon / .php-cs-fixer.php) were generated successfully from .dist templates.

Testing & Code Quality

• Coding style rules have been applied locally (composer cs:fix).
• Static analysis checks pass with no new regressions (vendor/bin/phpstan).
• I have added/updated unit or integration tests if applicable.
• I have verified these changes locally on a native PrestaShop environment.

CI/CD Deployment Context

• The CI pipeline passes fully on GitHub.
• For Release Branches: If this is a release/* branch, I am targeting the correct base branch to allow the automated apply-release version bumping job to run.

Pull request overview

This PR rebrands the library from PayPlugPluginCore to PayPlugPluginMcp, upgrades the development/runtime target to PHP 7.4, and refreshes the project’s tooling/CI configuration accordingly.

Changes:

• Renamed namespaces/autoloading from PayPlugPluginCore\ to PayPlugPluginMcp\ across src/ and tests/.
• Upgraded PHP/tooling baseline (Docker PHP 7.4, Composer PHP constraint, PHPUnit/PHPStan/PHP-CS-Fixer/CaptainHook) and raised PHPStan level.
• Updated CI/release workflows and local hooks/configs; adjusted refund flow to validate resource type via instanceof Payplug\Resource\Payment.

tests/Units/Gateways/Payment/StandardPaymentGateway/formatPaymentAttributesTest.php:11

• This test uses the PHPUnit group name "unit" (singular), while other unit tests use "units" and the Makefile target test-unit-units runs --group units. As a result, this test will be skipped when running that target.
