Subject: [PATCH] feat(nnx): Add Flax NNX PEFT/LoRA support and checkpoint
 resume

- Resolve pjit sharding metadata mismatches by re-evaluating state_mesh_shardings after parameter restoration and LoRA/QLoRA module injection.
- Update l2norm_pytree to skip non-inexact leaves (e.g. packed void arrays or WithAux wrappers).
- Implement normalized key translation (0 <-> layers_0) in checkpointing and model creation utilities for seamless parameter merging across NNX and Linen models.
- Add mesh axis shape sanitization for non-divisible dimensions.
- Include unit tests for l2norm_pytree void quantization, key translation, and upfront LoRA state restoration.
- Fix NNX sharding resolution regressions in multi-device mesh (composite pytree, scan axis, NamedSharding).
- Fix lora_utils_test regex assertions across 10 architectures for model lora_module_path.
- Update reference HLO baselines for JAX 0.10.2 compiler output.
