feat(refactor): add RenameLookupElement to improve ui support and cod…

…e completion #132 #129

This commit introduces a new class, `RenameLookupManagerListener`, which enhances refactoring support by adding post-action support and code completion functionality. The listener is designed to work with `LookupImpl` and `TemplateManagerImpl` to provide a more robust refactoring experience. It includes a list of suggestions (`suggestion1`, `suggestion2`, `suggestion3`) and adds them to the lookup with a custom `RenameLookupElement` that renders with the `AutoDevIcons.Idea` icon. This change improves the usability and functionality of the refactoring process.
