## Breaking changes

- This PR changes the interface for using turbulence closures that have prognostic tracers. Instead of adding these tracers manually, the tracers are added _implicitly_. As a result, any attempt to manually add closure tracers will result in an error.
- For example:

### Before this PR

```julia
closure = CATKEVerticalDiffusivity()
tracers = (:T, :S, :e)
model = HydrostaticFreeSurfaceModel(; grid, closure, tracers)
```

### After this PR

it should now be built with

```julia
closure = CATKEVerticalDiffusivity()
tracers = (:T, :S)
model = HydrostaticFreeSurfaceModel(; grid, closure, tracers)
```
