refactor(ai_client): classifier functions return ErrorInfo instead of ProviderError

Browse Source 
The 6 error-classifier functions in ai_client.py, openai_compatible.py,
and qwen_adapter.py now return ErrorInfo (data-oriented) instead of
ProviderError. Each takes a source: str parameter for telemetry
provenance. ProviderError class is still used in production code paths
(Task 3.4) and will be removed in Task 3.7.
