van-thermal grows sensor kinds beyond plain temperatures: "fan" alerts when
pwmfan is commanded on (pwm > 0) but reads 0 RPM (warn on first sample, crit
if it persists — 0 RPM with pwm 0 is just the firmware idling a cool SoC),
and "undervolt" goes crit on the live rpi_volt alarm plus a sticky warn off
the firmware's latched since-boot bit, so dips shorter than the 10s sample
interval still surface once. All kinds share the existing hysteresis /
journal / Pushover machinery (fan 🌀, undervolt ⚡).
Config adds nvme Composite (65/70), rp1_adc (80/85 — the RP1 die drives all
USB/eth I/O), fan, and undervolt to the existing cpu sensor. The CSV logger
now derives per-kind columns and self-rotates when the header changes; the
Cockpit Temps card renders RPM + pwm duty and undervoltage state alongside
the temperatures.

van-thermal fires its first sample seconds after start, and the Pi often
boots hot — order after network-online.target and retry network failures
in the Pushover send path (3 attempts, 15s apart) so that page survives
DNS not being up yet. Non-200 responses still don't retry.
The Quadlet gets StopTimeout=120: podman's default 10s window SIGKILLed
HA mid-flush and the recorder complained about an unclean sqlite shutdown
on every start. Verified clean after a full stop/start cycle.

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.
