feat(phase2): MLX decoder + refiner with parity tests
- MLP, DecoderHead (SegFormer-style), RefinerBlock, CNNRefinerModule
- All NHWC native, GroupNorm with pytorch_compatible=True
- Layout utils: NCHW<->NHWC, conv weight transpose (OIHW->OHWI)
- Dump script extended to export decoder/refiner weights
- Parity: decoder max_abs ~5e-6, refiner max_abs ~1e-5

feat(phase1): PyTorch reference harness + fixture tests
Dump script loads CorridorKey checkpoint, runs deterministic forward
pass (seed=42, 512x512), saves 14 intermediate tensors to golden.npz.
Includes pos_embed bicubic interpolation for resolution mismatch.
32 shape/dtype/range validation tests all passing.
