Add unit tests for traversal and utility functions

- Implement tests for traversal methods: even, odd, first, last, find, filter, has, index, next, prev, and their respective variations.
- Create utility function tests for each, extend, isFunction, isPlainObject, isWindow, map, parseHTML, and each.
- Ensure all tests cover various scenarios including edge cases for empty collections and non-matching selectors.
- Set up Vitest configuration for testing environment and module resolution.
