* WIP crew events emitter * Refactor event handling and introduce new event types - Migrate from global `emit` function to `event_bus.emit` - Add new event types for task failures, tool usage, and agent execution - Update event listeners and event bus to support more granular event tracking - Remove deprecated event emission methods - Improve event type consistency and add more detailed event information * Add event emission for agent execution lifecycle - Emit AgentExecutionStarted and AgentExecutionError events - Update CrewAgentExecutor to use event_bus for tracking agent execution - Refactor error handling to include event emission - Minor code formatting improvements in task.py and crew_agent_executor.py -
