pub fn thermal_tick()Expand description
Periodic thermal check for the decode hot path — samples a RESIDENT NVML governor and, per the
auto-cap user option, enforces (sustained Critical → apply the recommended cap; cooled → restore)
or recommends. Cheap (an NVML read); call every N decode tokens. No-op when the nvml feature is
off or NVML/the driver is unavailable. The resident governor keeps the auto-cap hysteresis state
(Critical streak, capped flag, saved limit) across ticks.
