The 0.1.50 guard only covered _read_gpu_temp_uncached's FIRST probe path;
its rocm/psutil fallbacks and gpu_eval() (which reads engine_gpu_stats
directly) still saw the raw 511°C and cooling-waited a healthy card
forever. Filter at the real source — the amdgpu sysfs temp1_input read
in gpu_detect — so temp is None for any ≥150°C reading and NO downstream
reader can act on it; plus a final chokepoint in read_gpu_temp().
