Strict mypy check fails on transcription response

[saxon134]

python -m mypy src tests fails because AudioResource.transcription() is annotated as returning APIResponse, while the committed test accesses the transcription-specific .text field (tests/test_client.py:165). APIResponse does not declare text, so the repository�\s strict mypy configuration cannot pass. Add a typed transcription response model with text and return it from transcription()/transcription_async(), or declare the field on the returned model.

Summary: missing transcription text model in audioresource.transcription

Coding Loop Plan

Refined Issue

Strict mypy fails because audio.transcription() returns the generic APIResponse, whose type does not declare the text field returned by /v1/audio/transcriptions.

Implementation Plan

Add a narrowly scoped Pydantic model for transcription responses, inheriting from the existing SDK base model so extra provider fields remain allowed. Give it the stable transcription field(s), including text, and use it only for the sync and async /v1/audio/transcriptions methods; leave speech and other generic audio responses unchanged.

Update or add focused tests for transcription to assert .text is typed/available, unknown provider fields are preserved, and both sync and async transcription methods return the new model behavior. Validate with strict mypy and the relevant existing client tests.

Development Tasks

1. Type audio transcription responses
   Add a dedicated Transcription Pydantic model with a required text: str field in src/globalrouter/_models.py. Import that model in src/globalrouter/_resources.py and change AudioResource.transcription() and AudioResource.transcription_async() to return Transcription and pass Transcription to request_model / request_model_async. Export the model from src/globalrouter/__init__.py if public response models are consistently exported there. Do not change unrelated audio speech or generic APIResponse behavior.
