Copied: libDF/src/lib.rs, libDF/src/tract.rs, libDF/src/transforms.rs unchanged; models/DeepFilterNet3_onnx.tar.gz
(the DeepFilterNet 3 model) unchanged. libDF/Cargo.toml trimmed: only the library with the `tract` and `default-model`
features; the dataset, training, binaries, Python bindings and C API (and their dependencies) left out; features that
name left-out parts kept as empty so the sources' `cfg`s still read.
