Autonomous sensor calibration and drift correction

Misalignment, drift, and correction math across real road segments.

Segment-by-segment calibration simulation for 25 autonomy stacks with sensor extrinsic drift, IMU bias, wheel slip, time sync error, EKF updates, Gauss-Newton refinement, SE(3) pose updates, and RTS smoothing.
