Fix sats being able to trigger nuke explosions

[Basilisk3]

Description of the proposed changes

Instead of the Novax being able to destroy nukes, the nuke now destroys the Novax satellite the majority of air units.

• This fixes an abuse which made it possible to destroy nuke launchers and bases with a falling satellite wreck. The chances of this occurring are rare, but it is possible.
• Nukes destroy all other low-hp air units, and the Novax satellite is a very low hp unit, so this solution is more coherent with the internal logic of the game.
• Rebuilding the satellite is cheaper than building a nuke, even ignoring the launcher. This fixes this balance issue.

This PR does not remove the "simulated projectiles" part of the game. The satellite dies when impacting on the nuke, just like any other low-hp air unit.

Checklist

• Changes are annotated, including comments where useful
• Changes are documented in the changelog for the next game version

As discued in the balace channle thier is no abuse to such mechanic due to falling sataline has falling randomness. as well as their is no balance created issues cureenly with the satalite. Do not see the need for nukes ignoring the satellite as it litlery falling from space at immense speed hense the missiles detonate.

As I explained on Discord, this is incorrect. Just because something is random, does not mean it cannot be abused.

Do not see the need for nukes ignoring the satellite as it litlery falling from space at immense speed hense the missiles detonate.

This is also wrong, the nuke does not ignore the satellite. The nuke destroys the satellite, in accordance with the game having simulated projectiles.

It's up to balance team to decide if sacrificing a satellite is fair to block nukes. To individually fix the absurdly rare chance of blocking a nuke using the wreck you can check self.Dead and return false in the satellite's script.
You could do a more casual nerf to this mechanic by increasing the costs, especially buildtime, of satellite to make it more fair when it does get used. This would create a real opportunity cost in not being able to use the satellite for a long time because you end up with a 19.5k mass difference basically sitting around doing nothing on your side. The mass difference of course isn't as large because of the let's say one extra t3 pgen the nuke user has to build, so you can consider adjusting the satellite energy cost too.
Here's the data for analysis:

Unit	Mass Cost	Energy Cost	Buildtime	Notes
Novax Station	36k	512k	44,800	300 bp
Satellite	10k	160k	30,000	Gains value slowly by being alive, can block nukes by being nearby when they are launched and then being microed to float right above them.
Nuke launcher	16.5k	412.5k	25,000	1500 bp
Nuke Missile	12k	1,500k	450,000
Yolona missile				takes 2 smd to intercept
SMD	7500	105k	5841	1080 bp
SMD missile	3.6k	360k	259,200

Thanks for your analysis. I read your post on discord. If you can control the trajectory of the wreck, then this is definitely something that should be fixed in my opinion.

I changed it so nukes still explode when colliding with satellites. The exploit is removed by preventing falling satellites from triggering nuke explosions. I prefer my initial solution, so this is a compromise.

@lL1l1 I can also move the changes over to the Defense Satellite's script file, as you suggested. The current solution would apply to all possible satellites though, which I would prefer.

I think it's fine to keep it in the main air unit script if it's only for falling satellites. Satellite units in general shouldn't be able to block nukes multiple times per life after all.

Thanks for taking the time👍
