Python SDK v6.6.0

Changed

• Renamed affected_traces_percent → affected_sessions_percent on the Signal (list) and SignalDetail (detail) response models (JSON alias affectedSessionsPercent). The value is the fraction of project sessions affected by the signal, in [0, 1] (sessions are the platform's primary unit); the previous name mislabeled a sessions-based ratio as traces. Update any code reading signal.affected_traces_percent to signal.affected_sessions_percent.
