/**
 * A reactive state and utility composable providing client-side data export capabilities
 * (Excel and PDF) for Nuxt Crud Table instances.
 * @remarks
 * It dynamically evaluates layout constraints, matches configuration-driven column exclusion lists,
 * maps raw structural keys into human-readable labels, and processes code splitting via lazy dynamic
 * imports (`xlsx`, `jspdf`, `jspdf-autotable`) to preserve a optimized bundle footprint.
 * @example
 * ```ts
 * const { isExportEnabled, exportToExcel, exportToPDF } = useNctExport()
 * if (isExportEnabled) {
 * await exportToExcel(usersData, 'users', ['id', 'name', 'email'])
 * }
 * ```
 * @returns An object containing the export activation flags and lazy formatting action triggers.
