Reuse the curated LTX-2 NVFP4 linear target set for QAT while preserving the existing Wan-style profile. This changes LTX-2 attachment from 1,344 broad substring matches to the 576 linears used by deployment.
Forward the role-local attention backend through LTX2Model so transformer construction remains compatible with the model-loader API merged in #1619. Add CPU parser/export reconstruction and target-profile coverage, hardware gates, and update the documented YAML surface.
