For me, word-final stops are generally not released, but I think
more commonly something like sandhi operates, so that "The
cat isn't asleep" turns out something like [D@ k_h&r* Idn=t
@slip], where [r*] is the something similar to the voiced tap.

Hmm... I'd agree with you, except that that allophone for me is
articulated farther forward in the mouth than what I normally associate
with the Spanish <r> (from my meager experience via TV and the
cleaning ladies and such... <sigh>).  Not quite dental, however.
