Problem

The .release-please-manifest.json was updated to version 2.8.0, but the plugin files (wp-graphql.php and constants.php) still showed version 2.7.0. This caused users to see update notices even after installing 2.8.0.

Solution

• Fix version numbers in wp-graphql.php and constants.php to match manifest (2.8.0)
• Move constant mappings from hardcoded JS to release-please-config.json for better maintainability
• Add comprehensive test suite for update-version-constants.js script
• Add integration test that validates all plugins from manifest automatically
• Update documentation for new constantMap configuration approach
