Daniel Han 133f6fecf7 Studio: harden video/diffusion cache, attention, and CFG-parallel fault paths
- diffusion_attention: arch-gate FlashAttention 2 to Ampere (SM80)+ in both the
  primary selector and the heterogeneous-replica guard (it crashed on pre-Ampere).
- diffusion_cfg_parallel: convert boolean attn masks to additive bias before the direct
  cuDNN op so partial masks match F.scaled_dot_product_attention; make proxy disable_cache
  transactional (clean both branches, mark broken, surface a reload-required error).
- diffusion_cache: fail closed when a magcache step-count resize or below-threshold
  disable cannot remove the old cache; surface a failed enable+cleanup instead of a false
  uncached None.
- video: roll back earlier experts when a later expert raises in the all-or-none step-cache
  loop; fail the load when the primary-only cache cannot be re-engaged through the
  CFG-parallel proxy; validate transformer_cache_quality and cfg_parallel before the worker.
- scripts: place the fp8 ablation pipeline on CUDA; fail closed on a failed magcache resize
  in the speedmem bench; label OOM distinctly in the SDPA mask probe.
- tests: regressions for the FA2 arch gate, transactional proxy disable, all-or-none
  exception rollback, magcache fail-closed transitions, and enable+cleanup failure.
