PWN::FFI::Volk

Thin VOLK (Vector-Optimized Library of Kernels) binding. Dispatches to SIMD kernels (SSE/AVX/NEON/…) when the host provides them. Used by PWN::SDR::Decoder::DSP hot paths so MHz-rate I/Q work stays off the Ruby GC heap while orchestration remains pure Ruby. Nothing here shells out and nothing is compiled at gem-install time — if libvolk is missing, .available? is false and callers fall back.

When to use

Call PWN::FFI::Volk from pwn_eval when the task needs this module. Do not reimplement it in shell.
