Feature: AgentID integration for per-agent identity tracking and observability

## Summary

Agent observability is the perfect place to track agents BY identity. AgentID enables per-agent monitoring with cryptographic identity, trust scores, and verification.

## Reference Implementation

[AgentID](https://getagentid.dev) is an open-source identity layer for AI agents:
- ECDSA P-256 certificates per agent
- Verification API for runtime credential validation
- Trust scores for authorization decisions
- Agent registry for discovery

We have built integrations for CrewAI, LangChain, and MCP.
