temphummon dev 96089c168f Verify internal temp sensor is live via CPU stress test 
- temp sensor confirmed responsive to die heating (27.6 -> 28.6 C under load)
- document quantization/calibration: readout sticks to ~1C steps ending in .6
  (inherent to ESP32-H2 internal sensor, not a bug)
- keep CPU_STRESS_TEST as a debug toggle (default off)
