Add WP-Compat PHPStan extension configuration

[swissspidy]

This PR integrates the WP-Compat PHPStan extension to enable WordPress compatibility checking in the codebase.

Summary

Added configuration and schema definitions for the WP-Compat PHPStan extension to validate code compatibility with WordPress versions.

Key Changes

• Added johnbillion/wp-compat dependency to composer.json
• Configured WP-Compat parameters in extension.neon:
  • Set pluginFile to null (default behavior)
  • Set requiresAtLeast to '4.9' (oldest supported WordPress version for WP-CLI)
• Added parametersSchema definition for WP-Compat to make the configuration available without explicitly loading the extension

Implementation Details

The schema definition allows both pluginFile and requiresAtLeast to be nullable strings, providing flexibility in configuration while maintaining type safety through PHPStan's schema validation.
