Yeah, I know about light being slowed down through various media and all that.  My question is WHY gravity takes any time to operate.  And just saying lightspeed is "the limit" doesn't work.  Until we know how gravity really works, we can't tell the speed.

Look at the observations.   If gravity waves were detected before an event, then they'd be travelling faster than light.  If they arrive a bit later, then they would be slower.   If they arrive at the same time then the gravitational waves must be travelling at the same speed as the light from the event they correlate to.

So what evidence is there that they travel faster slower or equal to light?

Very hard to empirically prove, since there are so few observations so far, and the early ones were black hole mergers which wouldn't produce much EM radiation ... but a year ago ...

We may soon be able to use stars as gravity wave detectors:

Maybe.  "acoustic spectra of these stars" ... if it weren't for the vacuum of space, the roar of the sun, not just the light, would deafen us all.
