NVMe drives run hotter than HDDs and kept firing the 48°C HDD alerts.
HDD tiers now exclude nvme devices; NVMe gets its own 65/70/75°C ladder.
The device matcher tolerates both "nvme0" and "/dev/nvme0" label forms
(smartctl_exporter strips the /dev/ prefix).

Provision Grafana Unified Alerting as code: ntfy webhook contact point
(?template=grafana), notification policy tree, and cumulative disk tiers
for HDD temperature (48-60C, <20C) plus ZFS/filesystem capacity. Lower the
smartctl exporter interval to 30m for alert responsiveness.
