Remove brainmaestro/composer-git-hooks and update PHP minimum to 8.4

[Copilot]

This PR removes the brainmaestro/composer-git-hooks dependency and its associated configuration from the project, and updates the minimum PHP version requirement to 8.4.

Changes

• Removed dependency: Removed brainmaestro/composer-git-hooks from require-dev section
• Removed hooks configuration: Removed the extra.hooks section that contained pre-commit and pre-push hook definitions
• Cleaned up scripts: Removed all cghooks-related scripts including:
  • post-install-cmd hooks that ran cghooks commands
  • post-update-cmd hooks that ran cghooks commands
  • cghooks script alias
• Updated PHP requirement: Added PHP 8.4 minimum version requirement to composer.json
• Updated CI pipeline: Updated GitHub Actions workflow to use PHP 8.4 for both phpcs and phpunit jobs

Why

The composer-git-hooks package provided automatic git hook management through composer, but this functionality is being removed from the project. All the essential development scripts (check-style, fix-style, test, phpstan, psalm) remain available and can be run manually or through other CI/CD workflows.

The PHP version has been updated to 8.4 to align with modern PHP standards and ensure the pipeline tests against the minimum supported version.

Verification

• ✅ composer.json validates successfully
• ✅ No references to the package remain in the codebase
• ✅ All other composer scripts continue to work independently
• ✅ CI pipeline configured to test with PHP 8.4
