Roberto Moura 8352b26c1a Fix lag when dragging a floating selection with the Move tool ...

- Replace whole-region Vec<f32> read_region/write_region in CutParts::new
  with tile-parallel cut_piece + try_fill_surface/try_clear_surface,
  sharing interior Arc<Tile> allocations in O(1) and activating the
  solid_tile hole-fill fast path on Background and mask targets.
- Cache piece_bounds on CutParts so CutParts::place avoids scanning tile
  content bounds on every drag frame.
- Parallelize composite_over across top tiles with Rayon and share fully
  opaque top tiles by Arc<Tile> clone in O(1), preserving COW tile
  identity for GPU canvas uploads.
- Parallelize Surface::translated across target tiles with Rayon and
  prune cleared tiles in-place inside edit_tiles.
- Skip zero-offset floating preview generation on pointer-down in
  move_ui::floating_doc.
- Exclude SnapKind::Selection when moving selected pixels with the Move
  tool so small initial drags do not snap back to (0, 0).
- Keep navigator_plain active during Move/Brush/Patch drags on a GPU
  canvas so navigator_gpu is not evicted into a synchronous full-document
  CPU thumbnail composite on the first drag frame.
- Parallelize row normalization in compose::render_reduced_in_bands and
  add a direct read_rgba_into fast path for unmasked Normal layers over
  an empty backdrop.
