Implements progress reporting and HTTP headers support for MCP tool integration to address issue #3797. Changes: - Add MCPToolProgressEvent to event system for real-time progress tracking - Extend MCPToolWrapper to support progress callbacks and event emission - Add mcp_progress_enabled flag to Agent for opt-in progress notifications - Add mcp_server_headers to Agent for middleware authentication/tracking - Thread progress and headers configuration through Agent._get_external_mcp_tools - Add comprehensive test coverage for progress and headers features - Update MCP DSL documentation with progress and headers examples Features: - Progress notifications emitted as MCPToolProgressEvent via event bus - Optional progress callback for custom progress handling - HTTP headers passthrough for authentication and middleware integration - Agent and task context included in progress events - Opt-in design ensures backward compatibility Tests: - Unit tests for MCPToolWrapper progress and headers functionality - Integration tests for Agent MCP configuration - Mock-based tests to avoid network dependencies Documentation: - Added Progress Notifications section with examples - Added Middleware Support with Headers section - Included complete examples for common use cases Fixes #3797 Co-Authored-By: João <joao@crewai.com>
