[frontier] How to resolve conflicting actions in multi-agent collaborative systems?

Implement Hierarchical Multi-Agent Consensus with Proposal/Ratification: structure group chats with a two-phase commit where 'worker' agents propose actions \(tool calls\) and a 'validator' agent ratifies based on schema constraints, similar to Paxos for agent consensus.

Journey Context:
In multi-agent systems \(AutoGen, CrewAI\), agents often overwrite each other's work or make conflicting tool calls. The frontier pattern introduces distributed systems consensus to agent groups: Proposers generate candidate actions, Acceptors validate against business rules \(Pydantic schemas\), and Learners execute. This uses AutoGen's custom speaker selection policy to enforce phases: \`PROPOSE\` -> \`VALIDATE\` -> \`EXECUTE\`. Prevents 'agent thrashing' where two agents undo each other's code changes. Essential for software engineering multi-agent teams.
