Worked on enhancing the Zoxide navigation feature in the yorukot/superfile repository, focusing on both test coverage and code maintainability. Expanded automated tests by adding cases for cursor navigation and render index updates, directly addressing previously incomplete coverage and improving reliability. Refactored code to replace magic numbers with descriptive constants and extracted repeated strings, increasing readability and easing future maintenance. Introduced new fields and expanded test scenarios to strengthen validation of navigation logic. Utilized Go for both development and testing, applying software engineering best practices to ensure robust feature behavior and clearer, more maintainable code throughout the navigation module.
