slice 9: GET /host/metrics + CPU/chassis-temp collector (v0.14.0)

Browse Source 
Add a host-wide, token-authed GET /host/metrics local-API endpoint that
re-serves the slice-4 collector's host + per-storage view to the customer
(the de-privileged controller can't read the host itself). Add the one new
collector — CPU/chassis temperature via sysfs hwmon/thermal-zones, graceful-
null — to the shared HostMetrics struct, so the hub report carries cpu_temp_c
too. Cross-repo host-report golden updated byte-identical.
