Kat, who has been diagnosed with cancer, has 4 years to live. She

classical SR, Kat's time slows to a half and ages only ~2.5 years,
arriving in Alpha Centauri, fairly bright eyed and bushy tailed, with
~1.5 years more of life.

But... also according to SR, during the space flight, inside the rocket
(Kat's inertial frame), its internal clock registers time normally, and
~5.0 years pass by for Kat before the landing at Alpha Centauri. She is
dead on arrival.

Nope. See:

http://en.wikipedia.org/wiki/Length_contraction

In Kat's inertial frame, Alpha Centauri is 2.18 light years
away from Earth, and approaching Kat at 0.866c. That makes
it a 2.5 year trip for Kat.

As Schrodinger would ask, is Kat alive or dead, when the rocket is
opened at Alpha Centauri? According to SR, she is alive and dead at
the same time. But there is no superposition in relativity, so
therefore, we have a contradiction,

Nope. Just another big red X through someone's attempt to
do a sophomore physics problem.

and relativity must be false, as
some 'nuts' have already known.

Get a clue already.
