[frontier] Static orchestration failing when agent capabilities change dynamically

Implement A2A \(Agent-to-Agent\) protocol skill discovery: agents advertise capabilities via JSON-LD manifests with input/output schemas, authentication requirements, and endpoint URLs before delegation; use semantic matching for dynamic routing

Journey Context:
Hard-coded agent topologies \(e.g., 'planner -> coder -> reviewer'\) break when specialized agents are substituted, upgraded, or temporarily degraded \(e.g., code-review agent with outdated style rules\). Naive routing assumes uniform capabilities and static endpoints. The A2A protocol \(open-sourced by Google, Anthropic, Salesforce coalition in 2025\) introduces capability negotiation: Task agents query Remote Agent manifests \(skills, versions, authentication schemes\) published as JSON-LD before sending tasks, enabling dynamic federation. This replaces brittle service meshes with semantic capability matching and supports ephemeral agent registration for serverless deployments.
