feat(mcp): add support for custom MIME types in tool responses

Browse Source 
Add capability to specify MIME types for MCP tool responses, with special handling for image content.

This enhancement allows tools to return different content types, particularly images, by:
- Adding a new toolResponseMimeType map property to configure response MIME types per tool
- Extending tool registration methods to accept and use MIME type information
- Adding special handling for image content in tool responses
- Updating documentation with the new configuration options
