Jacquerel f8c48e75cb Feeding the supermatter a nuke will make it explode (#90875) 
## About The Pull Request

Feeding the nuclear bomb (or its radioactive core) to the Supermatter
will cause an oversized radiation pulse, generate a large amount of
energy, and immediately damage the supermatter sufficiently to start
delaminating.
If the core isn't in the bomb it won't do this (meaning that the beer
nuke doesn't do it sorry)

I wish there was a nicer interface for these special supermatter
interactions but I also can't be bothered to figure one out right now

ALSO for some reason `consume_returns` was being called twice if a
living mob hit the crystal which seems like an unintended bug that has
been in the codebase for three years?
I fixed this but also doubled the values being passed into it because at
this point I guess those are the values we expect to get for mobs
running into the supermatter

## Why It's Good For The Game

Someone posted a clip today of a group of people pushing a nuke into the
supermatter and then it ate it and nothing happened.
That is sad, if you feed the supermatter a big bomb full of energy then
it should explode.

Damaging it immediately enough for it to explode might be over the top
in which case let me know, but having a movable bomb around is
reasonably uncommon if nukies aren't on the station as the station one
is not usually movable. Traitors extracting the nuke core also cannot be
done without a specific traitor objective giving you special tools.
Doing like 90 damage would, with a default supermatter setup, generally
just make it yell loudly but then slowly heal itself without any
required input which made me sad.

## Changelog

🆑
balance: The supermatter will react negatively to being fed nuclear
fissile materials
