/**
 * Extracts relevant headers for consent management from the request headers.
 *
 * @remarks
 * This function extracts geo-location headers (country, region) from various
 * CDN providers (Cloudflare, Vercel, AWS CloudFront) and normalizes them
 * into a consistent format for the c15t backend.
 *
 * The extracted headers include:
 * - Country headers (cf-ipcountry, x-vercel-ip-country, etc.)
 * - Region headers (x-vercel-ip-country-region, x-region-code)
 * - Standard headers (accept-language, user-agent, x-forwarded-*)
 * - Prefetch headers (purpose, sec-purpose, next-router-prefetch, x-middleware-prefetch)
 *
 * @param headersList - The Headers object from the incoming request
 * @returns An object containing the relevant headers for consent management
 *
 * @example
 * ```ts
 * import { extractRelevantHeaders } from '@c15t/react/server';
 *
 * // In your framework's request handler
 * const relevantHeaders = extractRelevantHeaders(request.headers);
 * ```
 *
 * @public
