Add camera-stitch preview and feature-matching script

- images/stitch-preview/north-sunrise-hstack.jpg:
  naive side-by-side preview of the two skycams at 14:29 on 2026-04-17
- images/stitch-preview/feature-matches-debug.jpg:
  close-up of overlap region (right 40% of north × left 40% of sunrise)
  with ORB Lowe-ratio matches drawn — 39 candidates, RANSAC survives only
  4 inliers because the 90° perspective offset invalidates a similarity
  transform.  Overlap IS present (trees, houses, power poles visible in
  both) but full homography needs more/better tie points.
- stitch-cameras.py: reusable script that generates both previews plus a
  similarity-transform .txt for reuse in ffmpeg filter chains once we
  have enough matches (or manual tie-points).
