feat(void): add xbps template for python3-pywhispercpp

Spec #16 ticket #26: Void template for the whisper.cpp Python binding, built from the pinned 1.5.0 sdist with the Vulkan backend (default-on option), shared libraries, and portable CPU flags. Includes the podman build/smoke harness, pinned base-image pins, and offline policy tests. Refs: #26
