The cargo-class push deliberately excluded the neural/semantic work to
avoid reverting origin; origin never independently changed neural, so
this brings it forward cleanly and wires it up.
- neural/mod.rs declares the full decoder family; rans.rs gains the
categorical decoder it needs (glc/mlicpp/elic/hyperprior/int_synth/
cmic/dcvc/snac + the JPEG-AI entropy/codestream/σ/value/filter port).
- runtime.rs uses the shared deterministic ort_session loader.
- Restores the semantic/generative path (semantic.rs, min_sim/sim_metric)
behind the `semantic` feature, with the bins/tests that construct
ModelRequirement updated accordingly.
- Re-adds byte-exact-conformance and the tools/ export/encode scripts.
Green together: wai-rs all features (75 lib + integration tests) +
clippy, byte-exact-conformance (8), wai-web wasm, wai-spz-gen.
