v0.3.0 — georeferencing accuracy

Multi-view GCP triangulation: marked pixels undistorted through the full COLMAP
lens model (SIMPLE_RADIAL/RADIAL/OPENCV/FULL_OPENCV/OPENCV_FISHEYE) into viewing
rays and intersected in least squares across all images a GCP is marked in, with
parallax + cheirality checks; single-view GCPs fall back to the nearest sparse
point. Solve-quality residuals (RMS 3D/horizontal/vertical, max, count) recorded
in georef_transform.json and surfaced in the log and the quality-report PDF.
Named CRS presets (Israeli TM, Palestine 1923, ETRS89 UTM 32N/33N = Germany's
official grid, OSGB, Swiss LV95) — presets, not defaults; an explicit CRS wins.
