Release 1.4.2 (#2965)

# Changelog

## New Features:

- **MCP SSE Support**: Added support for connecting to SSE MCP Servers.
- **Tool Hooks**: You can now have a hook that is wrapped around all
tool calls. This works for `Toolkits` and custom tools. See [this
example](https://github.com/agno-agi/agno/blob/main/cookbook/agent_concepts/tool_concepts/toolkits/tool_hook.py).
- **Team Session State:** You can now manage a single state dictionary
across a team leader and team members inside tools given to the team
leader/members. See [this
example](https://github.com/agno-agi/agno/blob/main/cookbook/teams/team_with_shared_state.py).
- **Cartesia Tool**: Added support for Cartesia for text-to-speech
capabilities.
- **Gemini Image Generation**: Added a tool that uses Gemini models to
generate images.

## Improvements:

- **PubmedTools Expanded Results**: Added expanded result sets for
`PubmedTools` .
- **Variety in Tool Results**: Custom tools can now have any return type
and it would be handled before being provided to the model.

## Bug Fixes:

- **Teams Shared Model Bug**: Fixed issues where a single model is used
across team members. This should reduce tool call failures in team
execution.
