Real VPAIR sample layout differs from the prior speculative adapter:
- poses_query.txt (not poses.csv) with ECEF xyz + Euler roll/pitch/yaw
- no native timestamps — synthesised at 5 Hz
- PNG images referenced by relative filepath
Adapter now uses coord helpers (ecef_to_wgs84, euler_to_quaternion).
Test fixture and conftest skip-reason updated to match.
Integration test xfail condition extended to cover large ATE values
when VO+GPR is not yet tuned for 300-400m nadir aerial imagery.
