Prevent stack overflow in recursive template resolution

[ezozbek36]

In manager.rs, the surely_template() method uses unbounded recursion to traverse template collections. Without depth limits, this could cause stack overflow with deeply nested or circular references.

Suggested fix: Implement a maximum recursion depth check and detect circular references.
