- Simplified structure validation by re-exporting functions from structure_config and validate_structure modules for better maintainability. - Consolidated validation logic in validate.lua, delegating to validate_package module for clearer orchestration. - Introduced new quick guide functionalities including step management (add, remove, update, reset ordering) and media handling (thumbnail and video URL validation). - Added utility functions for URL validation and step creation, enhancing the quick guide's usability. - Established type definitions for steps and media states to improve code clarity and type safety. - Enhanced schema editor with new field and relation definitions, providing a more robust structure for database schema management.
