I2P Transport Adapter
Integrates I2P eepsite protocol with Omnitoken manifest routing.
Allows Warden + omni:// to reach peers via I2P network:
- Automatic B64 destination key parsing
- Manifest-based chunk ordering (deterministic transport)
- Fallback routing when primary fails
- Attestation anchoring to I2P SAM bridge
Protocol: TCP SAM bridge @ 127.0.0.1:7656
Sessions: i2p_transport_[port]
Destination: B64 encoded 516-byte public key
