Adds two new macOS-only tables powered by powermetrics: - `macos_thermal_pressure`: exposes the OS thermal pressure state (Nominal/Light/Moderate/Heavy/Sleeping) and a derived `is_throttling` integer, using the `thermal` sampler with a 1000ms default interval. - `macos_soc_power`: exposes CPU, GPU, ANE, and combined SoC power draw in mW plus GPU active ratio, using the `cpu_power,gpu_power,ane_power` samplers with a 3000ms default interval for meaningful averages. Both tables accept a constrainable `interval` column. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Add TestThermalPressureGenerate and TestRunPowermetricsStatError to cover the Generate function and the non-ErrNotExist stat error path, bringing coverage from 38.7% to 67.7%. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
