The PyroWave bitstream carries no version field. The host and the client must be
built from the same pyrowave commit; the RTSP handshake advertises it as
PYROWAVE_BITSTREAM_ID in pyrowave_protocol.h.

Linux host patch: DMA-BUF memory import duplicates its input FD before Vulkan allocation,
consuming the original only after image creation succeeds. Failure leaves the input FD
owned by the caller, including failures after memory allocation. No bitstream changes.
