Replace parallel chunk strategy with sequential incremental assembly:
1. Start with first 20 images, full cpfind + optimize
2. Add 5 new images at a time with 5-image bridge to existing set
3. cpfind only on bridge+new group (small, fast)
4. Remap CPs to global indices and accumulate
This ensures spatial coherence: each new batch is constrained by
the already-stable panorama, preventing orientation flips that
occurred with the parallel chunk approach.
Images are sorted by azimuth, so consecutive indices = spatial
neighbors (guaranteed contiguity).
