Extensible Poka-yoke validation trait (implement per model type)

§Example

impl PokaYoke for WhisperModel {
    fn validate(&self) -> PokaYokeResult {
        let mut result = PokaYokeResult::new();

        // Gate 1: Filterbank must be embedded
        if self.has_filterbank() {
            result.add_gate(Gate::pass("filterbank_present", 20));
        } else {
            result.add_gate(Gate::fail("filterbank_present", 20,
                "Fix: Embed Slaney-normalized filterbank via MelFilterbankData::mel_80()"));
        }

        // Gate 2: Filterbank must be Slaney-normalized
        if let Some(fb) = self.filterbank() {
            let max = fb.iter().cloned().fold(f32::NEG_INFINITY, f32::max);
            if max < 0.1 {
                result.add_gate(Gate::pass("filterbank_normalized", 30));
            } else {
                result.add_gate(Gate::fail("filterbank_normalized", 30,
                    format!("Fix: Apply 2.0/bandwidth normalization (max={max:.4}, expected <0.1)")));
            }
        }
