fix: push explosion dice to DieTerm results so DSN displays them

Explosion rolls were evaluated as separate Roll instances but never
added to the original DieTerm's results array. Dice So Nice reads
DieTerm.results to render 3D dice, so explosions were invisible.

Now each explosion result is pushed into the DieTerm's results array
({result, active:true}), letting DSN render explosion dice in the
correct chronological order alongside the main die.

Applies to prompt(), promptRangedDefense(), promptRangedAttack(),
and rollSpellDamageToMessage().
