Mains Frequency Estimator

Harmonics-aware, EMA averaging (up to 60s), and a 5s warm-up gate before decisions. **Prefers 2× (100/120 Hz) over fundamentals** to handle mic high-pass filtering.

Decision is withheld until at least 5.0s of analyzed frames accumulate. After that, the classifier uses EMA-smoothed evidence where the 1st harmonic (2×) is weighted above the fundamental.
