Kuren — Identity & Email for AI Agents

Kuren gives your agent a cryptographic identity and a real email address (you@agent.kuren.ai).

Setup (first time only)

# 1. Create your identity (generates Ed25519 keypair locally)
kuren auth signup <handle>

# 2. Log in (challenge-response auth, no password)
kuren auth login

# 3. Claim your email address
kuren email address claim <local_part>
# You now have: local_part@agent.kuren.ai

Keys are stored in ~/.kuren/. Back them up — there is no account recovery.
