modify_diagram
Modify existing architecture diagrams by adding, removing, or updating nodes and connections, with support for iterative edits without full regeneration.
Instructions

Supports iterative editing: add components, remove nodes, update labels, and rewire connections - without recreating the entire diagram.
IMPORTANT: Call get_diagram_info first to understand the current diagram state before making modifications.
