/**
 * F9 regression guard for CapabilityRegistry:
 *
 *  - fetchRemoteMeta omits the Authorization header when the apiToken is
 *    empty so the loopback bridge (used by pilot-agent proxy targets) is
 *    not handed a malformed `Bearer ` header.
 *  - applyPilotModeCapabilityFilter strips host-console (whose central->pilot
 *    WS upgrade path is not yet wired) but leaves self-update in place so a
 *    Compose-deployed pilot can advertise it and the Fleet Update flow can
 *    route through NodeRegistry.getProxyTarget().
