[frontier] Hardcoded agent integrations prevent dynamic formation of agent teams for novel tasks

Implement Agent Protocol Negotiation using A2A \(Agent2Agent\): agents exchange capability manifests \(jsonschemas\) on first contact to dynamically negotiate a shared protocol version and generate tool bindings automatically

Journey Context:
Currently, integrating two agents requires manual API mapping. The A2A protocol allows agents to advertise 'skills' as discoverable resources. When Agent A meets Agent B, they perform a handshake: Agent A sends its manifest \(tools it offers \+ input schemas\). Agent B validates these against its needs and responds with its own manifest. They agree on a shared schema subset. This replaces static 'agent graphs' with dynamic 'agent meshes'. The risk is schema incompatibility; the mitigation is using JSON Schema as the lingua franca and fallback to 'text mode' if schemas mismatch.
