fix: materialize strided TP q/k/v views for the in-place GDN recurrent step
TP block-sliced value arrived as a strided view of the fused in_proj
buffer, silently failing the contiguity gate and routing every decode
step to FLA's out-of-place kernel (24 layers x state copy-back per
step = the 27 memcpy/st and half the recurrent state traffic seen in
the A100 profile). Materialize the tiny views instead.
