Validate public real-data pipelines

[rsasaki0109]

Summary

• validate SpatialRust 1.1.0 on the public 460,400-point PCL table scan through Rust PCD→COPC→bounds/LOD→MVP and Python clean→cluster→FPFH→ICP pipelines
• add an assertion-based Python real-data harness with dataset hash, structural counts, convergence, and transform-error gates
• strengthen the ignored Autzen HTTP COPC smoke so a non-empty bounded ROI is required and a full 10.6M-point download is avoided
• record the measured receipt and add the real-data E2E row to the roadmap

Root cause

The existing Autzen smoke selected a corner XY region plus a narrow Z slice. On the live dataset it returned zero points, but the test still passed because it only compared the empty ROI against a full download. The new central XY query requires 0 < roi_count < header_point_count.

Observed real-data results

• PCL file: 5,649,007 bytes, SHA-256 E285D415641E0D9DE695B611DB874CC8FE995E8089B77A50D6056D24D8CBCC58
• local COPC: 460,400 source, 76,919 ROI, 26 ROI+LOD, 54 plane inliers, 36 clusters
• Python: 4,004 outliers removed, 9,840 voxel points, 4 clusters, FPFH error 0.1124, refined error 1.0587e-05
• remote Autzen: 10,653,336 header points, 889,058 central ROI points
