Access Parent Network Intent Variables from Child Network Intent

Network Intents currently cannot reference variables or tables that were captured or computed in a parent Network Intent when a child Network Intent is executed. As a result, child intents must independently re-run commands to obtain data already available at the parent level. This enhancement would allow a child Network Intent to access select variables or tables from its parent, similar to how later canvases in a qApp can reference tables generated in earlier canvases. This would reduce redundant command execution, conserve memory in large-scale environments, and simplify troubleshooting of nested Network Intent logic.
