/**
 * `sheet.*` step implementations: thin dispatchers into the engine registry's edit
 * capability.
 *
 * @remarks
 * Internal sibling of the `@nhtio/adk/batteries/media` entry. The actual workbook surgery
 * lives in edit-capable engines (`engines/exceljs` preserves styling; `engines/sheetjs`
 * covers the wider read matrix but strips styling — SheetJS CE limitation). Each step here:
 * normalizes non-xlsx spreadsheet inputs to xlsx when the selected edit coverage requires it
 * (any spreadsheet-family MIME with a declared `hasConvert(mime, 'xlsx')` edge qualifies —
 * ODS/XLS via soffice or sheetjs, XLSB/FODS/SYLK/DIF/DBF/NUMBERS via sheetjs), dispatches the
 * op through `ctx.engines.edit`, and degrades to a model-actionable failure when no edit
 * engine is configured.
