Pull request overview

This PR addresses newly reported PHPStan type issues by adding an inline type assertion for the WordPress.org plugin info response, clarifying the expected structure of the plugin version data within the WP-CLI checksum command.

Changes:

• Added a PHPDoc @var array-shape annotation to assert $plugin_data contains a version: string key after runtime validation.
• Helps PHPStan understand $plugin_data['version'] is a string when used as a fallback version.
