Pull request overview

This PR refactors the codebase to use Fully Qualified Names (FQNs) more consistently, particularly in the visualization package. The changes improve code organization by consolidating node and IO processing logic and standardizing how FQNs are handled across the codebase.

Key changes:

• Consolidated node and IO processing into a new process_nodes_and_ios function in _process_nodes_and_ios.py
• Updated visualization code to use the FQN class instead of the fqn_to_object_ref function for better type safety and clarity
• Removed import aliases in test examples to ensure proper FQN resolution (e.g., b as B → b)
