/**
 * A composable utility that creates a reactive form state object initialized with
 * fields metadata and an optional seed dataset.
 * @remarks
 * This function processes field defaults and automatically standardizes date metrics into local time
 * strings formatted for compatibility with structural forms (`YYYY-MM-DDTHH:mm`).
 * @example
 * ```ts
 * const fields = [{ name: 'publishedAt', type: 'date' }]
 * const initial = { publishedAt: '2026-07-08T14:26:00.000Z' }
 * const formState = useNctFormState(fields, initial)
 * // formState.publishedAt will be formatted as: "2026-07-08T14:26"
 * ```
 * @param {{ name: string, type: string, required?: boolean }[]} fields - An array of metadata configurations representing form field items.
 * @param {Record<string, unknown>} [initialState] - Optional payload object containing pre-existing values used to hydrate form modifications.
 * @returns {Record<string, unknown>} A reactive Vue object map holding stateful properties key-value indicators.
