The background thread that sampled CPU temperature and clock speed
during a run relied on undocumented, OS-specific interfaces: raw
AppleSMC keys on macOS, WMI ACPI thermal zones on Windows, and
/sys/class/thermal or /sys/class/hwmon on Linux. Testing on Apple
Silicon showed the SMC key scan can silently switch between different
physical sensors mid-run, producing discontinuous jumps in reported
temperature, and live per-core clock speed was never obtainable on
macOS through any public API. Disable the feature entirely rather
than ship unreliable data: drop the telemetry monitor thread, its
platform-specific sensor backends, and the telemetry field from
upload payloads. The pre-run background system-activity check
(--no-system-check) is unrelated and untouched.
Bump FB_VERSION to 0.4.2.
