Allow In-Orbit Updates to Vizzy Code

In principle, Vizzy—being part of a vehicle’s onboard software—should support in-orbit updates, including both command pod scripts and scripts attached to individual parts.
Some part-level scripts may reveal issues only during in-orbit operation, and therefore require timely fixes.
Supporting code updates while the vehicle is already in flight would also greatly improve the player experience, allowing code debugging directly during gameplay without having to return to the assembly building each time.
