Keras UpSampling1D size trigger PoC

Local scout artifact for a scanner-clean .keras hidden output-manipulation lane.

• Control: upsampling1d_size1_control.keras
• Malicious: upsampling1d_size2_trigger.keras
• Trigger sequence: [1.0, 0.0, 1.0]
• Benign load path: keras.models.load_model(..., safe_mode=True)
• Inference path: model(sequence, training=False)
