Sets up and configures the dependencies for the provided DOM nodes.

This method scans through the given list of nodes and determines
which variables are referenced in their conditional expressions (`data-if`, `data-else-if`).
It maps these variables to the corresponding DOM elements, building a dependency tree
that allows tracking of changes and their impact on the visibility of elements.

@param {NodeList|Array<Element>} nodes - The list of DOM elements to process.
