Andreas WredeandClaude Opus 4.8 ef6c1ce182 thermal: van-thermal daemon (CPU+NVMe monitor, alert, log)
Single sysfs sample loop drives three jobs off one daemon (modeled on
van-failover):

- live state at /run/van-thermal/state.json; new Cockpit "Temperatures"
  card reads it in the existing 5s loop (no per-refresh `sensors` shell-out)
- journal alerts on ok<->warn<->crit crossings, with clear_margin hysteresis
- throttled, self-rotating CSV history at /var/log/van-thermal.csv

Sensors resolved by hwmon name+label (coretemp/Package id 0, nvme/Composite),
never by hwmonN index (not stable across boots). Defaults: CPU warn 80 /
crit 95, NVMe warn 65 / crit 70. deploy.sh installs + enables the service.
