This PR introduces cross-ecosystem architectural enhancements encompassing Graph Engineering, Loop Engineering, Context Management, and Prompt Frameworks.

What's Included

  • Graph Engineering: StateGraph implementations, A2A protocol support, and Cypher-like DSLs.
  • Loop Engineering: Async exponential backoff and retry handlers with strict context timeout support.
  • Context Engineering: Token budget optimizers prioritizing recent messages and system prompts.
  • Harness Engineering: Test harness wrappers for injecting mocks and running result validations.
  • Prompt Engineering: Secure text templating engines for LLM prompts.

All changes include appropriate edge-case handling for timeouts, cancellations, and state immutability.
