Capacity/auth/quota failover for cli-auto previously called select_route
with a hardcoded manual lane (cli-{alternate}-{effort}), so the retry
boundary was classified as switchyard-manual instead of going through
Jetson automatic classification, making the routing evidence misleading.
Now the retry calls select_route(context, "cli-auto", exclude_provider=...)
so the boundary stays automatically classified with an explicit
failed-provider exclusion. If the classifier reclassifies to a lower
effort than the original route, the lane re-pins the chosen provider at
the original effort floor so a capacity failure never silently downgrades
a high/xhigh task. Manual lanes (assignee != cli-auto) remain unchanged
and still fail closed without switching providers.
