Route recovery telemetry now includes normalized switch reasons and aggregate
reason counts, so load tests can distinguish peer failures, timeouts, and other
route-break causes.
`mesh-live-smoke` reports the synthetic route-recovery reason beside recovery
timing and switch count.
Endpoint ranking treats `capacity_limited` observations as a soft pressure
penalty instead of a hard recent failure, enabling load spreading without
marking the carrier unhealthy.
