Read the CPU temperature instead of the alarm threshold beside it

lm-sensors prints high= and crit= on the same line as the reading, so scraping
the line for its largest number reported a flat 100C on Intel while the shell's
last-field parse got a bare ")" and never fired at all. One parse in the
adapter now, preferring Tdie over Tctl since Tctl carries a +27C offset.
