Uses the gather shader from the APV encoder to copy the packet data on the GPU with a second pass. Replace all of that with a seg_gather compute dispatch in the same submission as the encode. It packs the per-slice slots tight and in order into a contiguous host-visible buffer, so the final packet is just the sum of the per-slice sizes and the gathered buffer is handed straight to pkt->buf with no extra submit, no copy, no CPU involvement. The slots are sized with the version-4 worst-case formula (the realistic lossless bound, ~17x tighter than the version-3 budget this encoder never approaches; the emitted bitstream version is unchanged) and rounded down to a 16-byte multiple so the gather reads them with aligned wide loads. Removes the transfer queue family, its exec pool, and the buf_regions scratch array.
