Daniel Han bb2b14db97 ideogram-4: build the FP8 text encoder at target dtype, size it as bf16-resident, optimize both DiTs
- The FP8 Qwen3-VL text encoder was constructed at the process fp32 default before the
  dequantized bf16 weights are copied in. That ~8B-param fp32 scaffold peaks ~2x on host RAM
  (loading FIRST, before the DiTs), so a 64 GB host can OOM. Build it at the target dtype under
  set_default_dtype, mirroring the DiT loader; rotary inv_freq is still computed in explicit fp32.

- The auto-policy memory table listed the text encoder at 8.8 GB, its FP8 on-disk size, while the
  DiTs were doubled to their bf16-resident sizes. The loader dequantizes the encoder to bf16 too
  (~16.3 GB), so the entry understated the resident footprint by ~7.5 GB and could let the planner
  pick a resident placement that OOMs. Size it as bf16-resident.

- Speed (regional compile, QKV fuse) and the attention backend only touched pipe.transformer, so
  ideogram-4's second denoiser (unconditional_transformer, run every step for dual-branch CFG)
  stayed eager/native while status reported the optimization as engaged. Iterate every denoiser DiT
  (mirroring the offload path) so both experts are optimized. Guarded on attr presence, so single-DiT
  families are unchanged.
