Changelog

New Features:

N1N Model Provider: Added n1n.ai as an OpenAI-compatible provider.
Knowledge: Added first-class Excel ingestion (.xlsx/.xls) by routing spreadsheets through the existing CSV reader, parsing workbooks per sheet into separate documents with sheet metadata.
Github/Sharepoint support: Added functionality in SDK and on API to support files in private github and sharepoint repos to be added to Knowledge.

Streaming metrics: Add collect_metrics_on_completion flag to only collect metrics from the final chunk.
Interfaces: Prevent errors on interfaces from ending up to the user facing message.

CustomEvent: Add tool_call_id to trace events back to their originating tool calls.
Knowledge metadata: Fixed to properly propogate metdata filters while using knowledge
Cerebras Model Provider: Fixed a 422 validation error when using Cerebras models with structured outputs (JSON schema format).
Team task delegation: Fixed a Python closure bug in Team.adelegate_task_to_members() where loop variables were not properly captured in async function definitions, causing all concurrent member agent runs to use the last member's values instead of their respective values.
Async generator tools: Handle async generator iteration exceptions gracefully by capturing the error on the tool call instead of re-raising, so the agent can continue and the model can decide how to proceed.
