hermes-agent/tests/gateway/relay/test_self_provision.py

"""Unit tests for managed-boot relay self-provisioning.

Covers gateway.relay.self_provision_if_managed() + the relay_endpoint() /
relay_route_keys() config readers. The connector HTTP POST is monkeypatched
(the cross-repo E2E exercises the real /relay/provision); these prove the
TRIGGER logic, in-process env wiring, and fail-soft boot behaviour.
