LTX-2 (LTXV 2.3) LoRAs have dual video/audio + cross-modal attention with
'*_attn.to_gate_logits'. The krea2 gate detector's '(?=[._])' lookahead let
the '..._attn.to_gate' substring match inside 'to_gate_logits', so LTX-2 LoRAs
were detected as krea2, ran through krea2 normalization (which renames
transformer_blocks->blocks), and then every key failed to map to the model
(1632 skipped, nothing merged). Require a '.' after the gate/proj leaf — always
the LoRA suffix in real krea2 keys — so LTX-2 falls through to the existing ltx
detection (transformer_blocks + attn1/attn2) and its pass-through normalizer.
No version bump (detection-only fix; correctly-detected arches unaffected).
