Changes in version 0.1.0                        

  - check_spatial_leakage() now computes train/test distances in blocks
    with vectorized haversine calculations instead of a pair-by-pair
    loop. Results are unchanged, and memory use stays bounded on larger
    datasets.

Initial release

  - Added diagnostics for temporal leakage, shared sensors, spatial
    proximity, and overlapping temporal windows.
  - Added a combined environmental sensor leakage audit workflow.
  - Added example environmental sensor data and documentation.
