📄 Description

Describe your changes

sysInfo on macOS scanned the entire ioreg -l output with substring matches for keys that do not exist on Macs ("ModelNumber", "device manufacturer"), so product name and manufacturer were effectively never reported, and the serial-number substring match could pick up unrelated keys.

It now runs /usr/sbin/ioreg -rd1 -c IOPlatformExpertDevice and parses the exact IOPlatformSerialNumber, model, and manufacturer keys, handling both quoted values and the <"..."> data-string form, and preserving = characters inside values.

Added table-driven tests covering the quoted and data-string forms, exact-key matching against similarly named keys, missing values, and values containing =. Real Apple Silicon output was checked with the serial redacted; the Intel format is fixture-tested. Verified with go test -count=1 ./client/system and git diff --check.
