Claude review instructions:
Added new files (.png) images the PR branch , so won't be able to find on main branch , ignore file not found.
the purpose of this PR is to resolve above Issues, as well as imporve Documentation with above process flows diagrams in PNG image format.
added to assets folders.
I have add process flow for:
1) autopattern
2) randompattern
3) manualpattern
4) defaultpattern
5) roundrobinpattern

pattern cookbooks:
1) context-aware routing
2) escalation
3) feedback_loop
4) hierarchical
5) organic
6) star hub spok
7) sequential
8) redunrant
9) traige with task

- Also updated process_message_before_send() hook information, along with image information

fix: naming conventions

* refine: process flows

added context_based_handoff.png , groupchat_manager.png, llm_based_handoff.png. also refined process flows images for sequential pattern , starpattern example , triage_tasks_example. i am keeping the process_notebook line commented as a choice of how i want to build the documentation, so ignore the commented line. I guess now we can approve with  5 star rating

* rollback: python3 -> python

* python3 > python for docs serve

* fix: added back operator

add back operator to, all referances to images are present and none are broken,we can approve this pull.

This blog post introduces the A2A (Agent2Agent) Protocol support in AG2 v0.10, covering:
- Overview of the A2A protocol and its use cases
- Practical implementation example with distributed code review
- Cross-framework interoperability with Pydantic AI and other frameworks
- Client implementation patterns (CLI, FastAPI, multi-workflow)
- Implementation considerations (async interface, error handling, authentication)
- Performance optimization and monitoring strategies
- Production deployment configurations

The post provides developers with practical patterns for building distributed agent systems that communicate across different processes, frameworks, and languages.
