5. Transfer to a plate and cool to room temperature.
6. Bring cream to a boil in a 1- to 2-quart saucepan, then pour over chocolate in a heatproof bowl, whisking until chocolate is melted and smooth.
7. Whisk in chocolate-hazelnut spread until combined, then whisk in nuts and remaining 1/8 teaspoon salt.
8. Pour filling onto cooled crust and put in freezer until just set, about 25 minutes. (Tart should not be frozen.)
