tinybert-address-autofill (v0.2.2)

Firefox address-autofill field classifier, retrained from the jt4qd v2 baseline without the ** input-type marker (strip_type_marker=True) so training matches Firefox inference. jt4qd params (bb, encoder_layers=0, pooling=cls, lr=3e-5, batch=64, epochs=25). Training data: current/refreshed train/val/test. Offline (no-**): total 0.8897 / close 0.9133. Only onnx/model_quantized.onnx (q8) is shipped.
