A missing policy-limits response with no cache no longer counts as a failure; the session runs with no restrictions instead.

In the policy-limits fetch/cache loader, a 404 or an unsolicited 304 response with no local cache is no longer treated as a hard fetch failure. The client logs Policy limits: ${n.httpStatus} with no cache, no restrictions for this session (not persisted), applies an empty restriction object for that session, and records telemetry as route_missing_fail_open or unsolicited_304_fail_open. This fail-open path is gated by tengu_rustling_orbit, which defaults to off in the resolved gate table, so failing open is the default shipped behavior; turning the gate on remotely falls back to the old failure-closed path instead.
