feat(anomaly): overround-compression detector
Adds the 4th IAnomalyDetector: flags a sharp drop in the bookmaker's
overround (raw implied-probability sum / margin) over a continuous live
window. Informational/non-directional — excluded from outcome grading
and backtest staking via AnomalyKind.IsDirectional().
- OverroundCompressionDetector: sliding-window scan mirroring SteamMove,
score = min(1, compression / 0.10 reference), suspension-gap aware.
- MatchWinEvidence.Probabilities gains Overround (pre-normalisation
margin); evidence JSON shape unchanged.
- Wired into DetectAnomaliesUseCase fan-out; AnomalyOptions + appsettings
(window 120s, threshold 0.02); en/ru resx + KindLabel arms.
- 11 detector tests incl. score saturation/scaling, inclusive threshold
boundary, and a three-way (draw-leg) overround case.
