ns-name is pure over get + symbol. aget/alength read jolt's mutable backing arrays (nth/count), and aset writes a slot through jolt.host/ref-put!; both handle the multi-dimensional form by walking. The array constructors (object-array/make-array/to-array/...) stay native — they build the mutable backing. Added array spec cases; ns-name already covered.
