feat: allow explicit variable bound to be passed to Name

[tlambert03]

this allows for directly providing the type to which a Name expression evaluates to:

from app_model.expressions import Name

is_running = Name("is_running", bound=bool)
reveal_type(is_running.eval())  # Revealed type is "builtins.bool"

@jni or @Czaki ... do you guys know what might be going on with the failed napari test here? https://github.com/pyapp-kit/app-model/actions/runs/14710881217/job/41282696495?pr=241

[jni]

It's napari/napari-plugin-manager#151, sorry about that! Looks like a fix is incoming. (napari/napari-plugin-manager#152) 🙏

[jni]

(ie safe to ignore the failure, will be fixed separately)
