A2A Executor Patterns

Purpose: Provide production-ready executor patterns for implementing Agent-to-Agent (A2A) protocol task handlers with proper error handling, retry logic, and execution flows.

Activation Triggers:

• Implementing A2A protocol executors
• Building task handler functions
• Creating agent execution flows
• Managing task lifecycle and state
• Implementing retry and error recovery
• Building executor middleware
• Task validation and sanitization
