v2.5.14

# Changelog

## New Features:

- **Fallback Models:** Added support for Fallback Models on Agents and Teams. See [docs](https://docs.agno.com/models/fallback-models)
```python
agent = Agent(
    model=OpenAIChat(id="gpt-4o", base_url="http://localhost:1/v1", retries=0),
    fallback_models=[Claude(id="claude-sonnet-4-20250514")],
)
```
- **Azure Blob Storage:** Added SAS token authentication support for `AzureBlobConfig`.
- **SlackTools:** Added workspace search tool to `SlackTools`.

## Bug Fixes:

- **LearningMachine:** Fixed to filter non-conversational messages from learning extraction.
- **OpenAIResponses:** Fixed to use correct MIME type for image bytes in OpenAI Responses API.
- **Claude:** Add automatic trailing user message injection for Claude 4.6+ models that don't support assistant message prefill, with centralized detection across all providers (Anthropic, Bedrock, Vertex AI, LiteLLM).
