Introduces new core abstractions and module management classes, adds several new modules (modern cache, REST API, SEO enhancement), and removes deprecated/disabled assets and code. Updates vendor dependencies, including Symfony components and php-opencc, and cleans up related files. This refactor improves code organization, extensibility, and modernizes the plugin's architecture.
