- README Quick Start: format `duration[0]` instead of the ndarray itself
(numpy refuses `f"{ndarray:.2f}"`; matches official `dur[0]:.2f` pattern)
- py/example_pypi.py: print synthesized duration to mirror the docstring example
- Add `"na"` to AVAILABLE_LANGS / Languages.Available / availableLangs
across all 11 runtimes (Python/Node/Web/Java/C++/C#/Go/Swift/Rust/Flutter/iOS)
so the language-agnostic fallback advertised in the README actually passes
per-runtime lang validation before being sent to the v3 ONNX duration predictor
