A GPU is named from an embedded PCI ID table, the same on every machine

Browse Source 
The router has no lspci, so its GeminiLake chip came up as 'Intel GPU
3185' beside the identical chip's 'Intel UHD Graphics 600' on hamtv.
A trimmed pci.ids — the graphics devices of Intel, AMD and NVIDIA, and the
virtual GPUs, 115 KB — rides in the binary and is consulted first; lspci
is the fallback for a card newer than the table. scripts/pci-ids-gpu.sh
regenerates it from the hub's copy.

`internal/metrics/pciids_gpu.txt`, regenerated by `scripts/pci-ids-gpu.sh` from the hub's
`pci.ids`): `gate` has no `lspci` and showed "Intel GPU 3185" beside `hamtv`'s "Intel UHD
Graphics 600" for the identical chip. The table is tried first everywhere, so the name — and
the sensor ID built from it — does not depend on which distro's pciutils a machine has;
`lspci` is the fallback for a card newer than the table. Two fixes the same evening:
the gpu box's layout rules had been lost from the stylesheet (v0.1.0-166/167), and on
`grid` the sampler hung for 42 minutes in Go's poller on the Arc's `fan1_input` —
`readStr` now uses plain blocking syscalls and each GPU's sysfs reads run under a
3-second deadline (v0.1.0-168; `hamlet/docs/gotchas.md` has the mechanism).
