/**
 * Worksheet check — the largest and most important part of the validator.
 *
 * Covers four new structural checks beyond the original wiring check:
 *   1. **Child element ordering** — `<worksheet>` children must appear in
 *      the ECMA-376 canonical order. Excel is known to reject files with
 *      out-of-order children; this is a top cause of "Excel needs to
 *      repair" prompts.
 *   2. **Cell `r="A1"` consistency** — every `<c r="…"/>` inside a
 *      `<row r="N"/>` must decode to row `N` and to a column in
 *      `[1, 16384]` (Excel's max column limit, XFD).
 *   3. **Merge region overlap** — every `<mergeCell ref="A1:B2"/>` must
 *      parse and no two merged ranges may overlap.
 *   4. **Style / SST index bounds** — every `<c s="N"/>` must reference a
 *      valid `cellXfs` index, and every `<c t="s"><v>N</v></c>` must
 *      reference an existing `sharedStrings` index.
 *
 * Plus the legacy r:id wiring checks (controls, drawing, comments,
 * hyperlink, tablePart, legacyDrawing) and the "controls without
 * drawing" repair signal. The old "legacyDrawing-after-controls" kind is
 * kept for backward compatibility — it is emitted in parallel with the
 * generic `sheet-child-out-of-order` kind.
