Per-package RAPL watts in the sample, the process table and as cpu.package.N.power
sensors. The socket rows collapse with an arrow; the fold is remembered per browser.

New sensor cpu.power: watts from the RAPL energy counters (Intel, and AMD
Zen through the same driver), summed over every package and averaged into
history. Parts of a package, psys and the MMIO duplicate are left out.
The counters are root-only, so a daemon that isn't root reads them through
`hamlab cpu-energy`, a root helper started once with sudo or doas and asked
over a pipe each sample, the same shape as the GPU client walk's helper.
It reads only the counters it finds itself. No counters or no root means
no reading, and the CPU box shows nothing extra.
