The task
The goal is to introduce a cost‑aware casting mechanism. Each query compiler should be able to declare how expensive it is to move its state to another compiler type. A new `QCCoercionCost` enum should define standard cost levels between `COST_ZERO` (no migration) and `COST_IMPOSSIBLE` (1000). This enum must be…
