GpuTelemetry fields

Field	Meaning
vddcr_gfx_v	Core voltage (V)
vram_temp_c / gpu_temp_c	Temperatures (°C)
power_w	Power (W)
gpu_clock_mhz / mem_clock_mhz	Clocks
fan_speed_pct	Fan %
mem_util_pct	Memory util %

to_rails() exports ("VDDCR_GFX", vddcr_gfx_v) for neuromorphic consumers.

Read path

1. Unless --force-software-only, try real sensors (nvidia-smi / NVML path).
2. Else use simulated “healthy idle” values (e.g. ~25 W, ~0.7 V core).

HardwareBridge::read_telemetry();
HardwareBridge::read_telemetry_force(force_software_only);
HardwareBridge::is_gpu_healthy();
