Commit Message

fix(s2): align CellUnion intersection/difference with upstream S2

- Stop post-normalizing intersection, intersection_with_cell_id, and
  difference; document sorted-input and normalized-output contract.
- Add debug_asserts mirroring C++ ABSL_DCHECK (sorted inputs, validity,
  normalization invariant when inputs are normalized).
- Match GetDifferenceInternal child recursion (four children via
  child_begin/next loop).
- Expand are_siblings comments to match upstream; add tests for denormalized
  intersection, intersection_with_cell_id scan path, and related cases.

Made-with: Cursor
