Note

Low Risk
Only adjusts exception message strings to add context; no functional changes to request/response handling or retry logic.

Overview
Improves error traceability in paperqa_nemotron/api.py by including the originating tool_name in exception messages for NemotronLengthError (when the model returns finish_reason == "length") and NemotronBBoxError (when tool-call arguments fail Pydantic validation).

This is applied consistently across both the Nvidia API and SageMaker execution paths, without changing control flow or parsing behavior.
