Pull request overview

Ports temporary-memory operations in the stochastic DFT (sDFT) PW module to DSP-specific multi-threaded memory ops (*_op_mt) when building with __DSP, aligning sDFT’s allocations with the DSP memory-management approach used elsewhere in the codebase.

Changes:

• Switch sDFT temporary memory helpers to resize_memory_op_mt / set_memory_op_mt / delete_memory_op_mt under __DSP.
• Keep non-DSP builds using the existing resize_memory_op / set_memory_op / delete_memory_op.
• Minor docstring whitespace cleanup in sto_iter.h.
