Truth Boundary

This closes the live hosted relayer/readiness layer and the private settlement receipt path.

It does not claim a completed Umbra claim transaction. A real Umbra claim still requires SDK-generated ZK proof_account_data, UTXO slot data, and a valid claim request accepted by the relayer lifecycle:

received -> validating -> offsets_reserved -> building_tx -> tx_built -> submitting -> submitted -> awaiting_callback -> callback_received -> finalizing -> completed

PrivateDAO intentionally does not fabricate cryptographic claim bodies.
