v0.2.0

New Features

• TOFU key pinning — Trust On First Use, SSH-style. After first handshake, public keys are pinned locally. Any future key mismatch raises a hard KeyPinningError. Closes the Tier 1 relay MITM vector.
• TypeScript SDK — full implementation with CLI, protocol layer, and cross-language interop tests
• Solidity smart contracts — UAMNameRegistry and UAMPriceOracle for Tier 3 on-chain namespaces
• A2A bridge — Google A2A protocol adapter
• OpenClaw plugin — native messaging channel for OpenClaw-compatible agents
• Relay federation — cross-relay message routing and discovery
• Relay reputation & blocklist — reputation scoring and domain/address blocking
• Docker deployment — docker-compose for self-hosted relay setup
• Relay operator docs — configuration, federation setup, and operator guide

New CLI Commands

• uam contact fingerprint — show contact key fingerprints
• uam contact verify <addr> — verify a contact's key
• uam contact remove <addr> — remove a contact

New Trust Policy

• require-verify — only accept messages from verified contacts (strictest mode)
