Add pipewire recipe

Fetches PipeWire 1.6.7 and drives its Meson build directly (via a pinned,
sha256-verified Meson source release, no system pip install), producing a
minimal client-only libpipewire-0.3 for consumers that just need to talk to
a running PipeWire daemon. Linux-only (DEP_PLATFORMS linux-x86_64/aarch64).
