Adds configurable event.require_rapid_drop (default off), require_lower_body (default off) and horizontal_angle_threshold_degrees (default 45). With the lenient defaults a sustained horizontal pose alone enters SUSPECT and confirms after the confirm window, which is now the main false-positive guard; missing knees/ankles no longer reject the pose. Thresholds flow into config_version. End-to-end smoke confirms a lying pose; 70 tests pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
