Both replace what a block allocates, which crashes aimdo's compiler (seen on a
rental with v4's shadow negative). Attached to the model, so any sampler.

v4 read the prompt length from transformer_options['c_crossattn'], which
ComfyUI never sets, so every block fell back to stock. It also stood down on
any i2v scene (per-token mod rows). Both fixed; tested on a real tiny H3.

Block repeat's video-only mode now really keeps audio single-pass: H3 blocks
write in place, so v4 restored audio from an already-repeated stream.
