v2.4.1

# Changelog

## New Features:

- **N1N Model Provider:** Added [n1n.ai](http://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.

## Improvements:

- **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.

## Bug Fixes:

- **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.
