Switch to mlprogram backend with ANE/GPU support

Changes:
- Converted both encoders to CoreML mlprogram (modern backend)
- Disabled fuse_transpose_matmul pass to fix NaN on transformer attention
- Forced FLOAT32 precision to avoid convolution overflow
- Target: macOS 14+ / iOS 17+ for full ANE compatibility
- Numerically verified: audio cos_sim = 1.00000036, text cos_sim = 1.00000012

Note: .mlmodel (neuralnetwork) replaced by .mlpackage (mlprogram)
