Merge a Nuke script: Auto Merge, Spawn Upgrade

Merge progression and base locking work as two separate paths. Auto Merge handles the repeated merge action, while the spawn and tier controls shape the progression around it. The lock controls sit outside that loop, so you can adjust growth without treating base access as part of the same setup.

How the Controls Connect

Start with the merge loop. Spawn and tier upgrades belong to its progression path; automatic locking and lock upgrades form the defensive path. That split keeps the menu easier to read and tune.
