crosstyan 6d3c5cc5c1 feat(cli): add depth verify/refine outputs and tests
- Retrieve depth + confidence measures from SVOReader when depth enabled
- Compute depth residual metrics and attach to output JSON
- Optionally write per-corner residual CSV via --report-csv
- Post-process refinement: optimize final pose and report pre/post metrics
- Add unit tests for depth verification and refinement modules
- Add basedpyright dev dependency for diagnostics
