Removed CPU telemetry (background temperature and clock speed sampling during benchmark runs). It relied on undocumented, OS-specific interfaces (raw AppleSMC keys on macOS, WMI ACPI thermal zones on Windows, /sys/class/thermal and /sys/class/hwmon on Linux) that proved unstable and inconsistent across operating systems and hardware, and live per-core clock speed was never obtainable on macOS at all through any public API. Rather than ship telemetry data that can silently jump between physical sensors mid-run or simply not exist on a given platform, this release disables the feature entirely: fossbench.net no longer accepts or displays it, and the client no longer collects it. The one-time background system-activity check (CPU/memory/process sampling before a run) is unaffected and still available via --no-system-check.
