Why does my car make no boost with the wastegate safety-wired closed?

It really sounds as if your wastegate valve.
If anyone is located near you run a second boost gauge off the turbo and to the wastegate, or straight into the gauge. See what boost the turbo is running off.
I am wondering if maybe you just have a bad turbo? The odds are against it but doesn't mean the the T-25 died and the GT25 was DOA.

Can a turbo spin freely, have minimal shaft play, and still be bad?
Again, the wastegate is wired closed.

Why would I care about an exhaust leak? That won't cause the turbo to suddenly stop making boost, would it?
Hotside = piping between the turbo compressor and the intercooler
coldside = piping between the intercooler and the throttle body
I'm going to give PR Motorsports a call on Monday. I'll let you all know what the cause of this was.

I've been building this car for a year, and it's only been running for 6 weeks, and I leave for college in 3 weeks and the car fails? **** that. I want to drive the thing, not chase some bullshit ghost problem.

Normally No if the turbo spins free and has minimal shaft play then normally the turbo is fine, but i think your problem goes pass normal. Maybe one of the interal seals on the turbo is shot and causing it not to build pressure but the bearings maybe fine.... again not a normal thing but I have heard of one turbo back in the DSM world that someone had that one of the seals was bad but the bearing was fine.
IF you know anyone around you with a working t-25, pull it from their car swap it to your and see if corrects the problem. Otherwise I am completely out of ideas man.
Good luck and please tells us what the cause is.
