Both halves now go through nodes we already own, so nothing third-party has to
be installed for the feature to exist.
The diffusion loader gains `chunk_causal`, which RE-CLASSES an already-loaded
H3 in place. That is what removes the need for a separate loader entirely: the
alternative is reimplementing ComfyUI's whole diffusion-model load path so the
adapter can be attached before the ModelPatcher exists and its memory ledger
counts it. Re-classing adds no parameter, renames no key and copies nothing —
only which forward runs changes — so the ledger and offload accounting are
untouched and the switch is idempotent.
The adapter is then an ORDINARY LoRA through FunPack Apply LoRA Weights. Our
loader already scores prefix variants against the model's real key map; it just
did not know this one. RAVEN's keys are `base_model.model.dit.<path>`, so
stripping only `base_model.model.` left `dit.` in front of every key and the
whole file matched nothing, silently. One entry in LORA_KEY_PREFIXES fixes it.
A ComfyUI too old for H3, or a non-H3 model, declines with a reason rather than
raising — one optional switch must not turn the loader into a dead node.
Tests: 1751 passed.
