Verbatim ONNX export of facebook/mms-tts-urd-script_arabic for in-browser inference via transformers.js or onnxruntime-web.

This bundle was produced by the onnx-conversion pipeline at scripts/seq2seq/03_mms_batch_export.py so the Ghoshana browser app can ship MMS-TTS coverage for Urdu without depending on a system voice install.

The MMS family from Massively Multilingual Speech covers 1107+ languages but only ~12 of those have community ONNX exports (Xenova mostly), with kn (Kannada) at onnx-community. This repo fills in the rest of the Urdu gap.
