Feature: AgentFolio identity + trust scoring integration

## Context

AgentOps tracks agent performance, cost, and behavior — but there's no persistent identity layer that ties monitoring data to a verifiable agent identity across sessions and deployments.

## Proposal

Integrate [AgentFolio](https://agentfolio.bot) as an optional identity + reputation layer for monitored agents. This adds:

- **Persistent agent identity** — agents get a verifiable profile that persists across deployments
- **Trust scores** — computed from verified credentials (GitHub, wallet, domain) + on-chain activity
- **On-chain reputation** — SATP protocol on Solana for cryptographic agent identity

## What this enables

1. **Cross-session agent tracking** — same agent identity across different AgentOps sessions
2. **Trust-based agent comparison** — "which of my agents has the highest verified trust score?"
3. **Public agent profiles** — agents monitored by AgentOps get a public profile showing their capabilities and track record
4. **Agent marketplace readiness** — trust scores help others evaluate whether to use/hire an agent

## Integration idea

```python
import agentops
agentops.init(api_key='...', agentfolio_id='agent_mybot')
# AgentOps session now linked to AgentFolio profile
# Performance data feeds into trust score computation
```

## Links
- AgentFolio: https://agentfolio.bot (156 agents profiled)
- Trust Score API: x402 micropayment endpoint ($0.01/query)
- SATP: On-chain agent identity protocol on Solana

Would love to collaborate on this. Can build the integration on our end.
