Parallelizes MiniMax-H3 Video VAE encoding across ranks using the balanced P2P tile path, and extends vae_use_compile to the encoder. T2AV is unaffected because it does not use the encoder; image-conditioned tasks such as I2AV see limited impact, while Ref2AV benefits substantially because it encodes long reference videos.
