Victor Kuznetsov c1971a3e8d feat(invisible): region-targeted regeneration for AI-enhanced composites
For AI-enhanced composites (digitalSourceType compositeWithTrainedAlgorithmicMedia,
identify ai_source_kind == "enhanced"; roadmap P1#8): regenerate ONLY the AI
region and preserve the real photo elsewhere, instead of regenerating the whole
frame.

- noai.tiling.feather_region_composite(base, regenerated, box, *, feather): pure,
  model-free compositor that blends the regenerated AI box back over the original
  with a feathered seam, leaving pixels OUTSIDE the box exactly equal to base.
  Fully unit-tested (outside-box exactness, interior == regenerated, hard paste at
  feather 0, monotonic seam ramp, dtype/grayscale/clamp/empty-box/shape-mismatch).
- WatermarkRemover.remove_watermark(region=, region_feather=) and the module-level
  convenience function thread it through: the remover regenerates (or tiles) the
  frame, then composites only the AI box back over the original input. The box is
  caller-supplied -- a C2PA composite manifest carries no reliable machine-readable
  region, so none is fabricated. The no-model lossless region path stays
  region_eraser.erase.
