	Ensure that [input] points to a local copy that can be changed without modifying the actual source of the input Should only be needed to ensure that legacy [dispatch_code] code can act as before, where it always was a copy.

Detailed Description

Reference (sequential, scalar) dispatcher for TileCopyNode.

Emits the whole copy as one sequential loop over the flat tile: for c in [0, size): dst[dst_geo(c)] = src[src_geo(c)], addressing each side by the plan's Layout::resolve_element. The {_dst,_src} inputs are the base pointers, so both sides are reinterpreted to a flat element pointer and indexed linearly. Used on the host (CPU private copy) and as the fallback where no cooperative/async atom applies; GPU targets register their own dispatcher for the offload atoms.
