/**
 * Builds a map of locale → URL for hreflang alternate links, suitable for
 * Next.js Metadata `alternates.languages`.
 *
 * Bridges SEO and i18n: for each configured locale that the document has a
 * slug in, it produces the locale-aware path (via buildLocalizedPath),
 * optionally prefixed with an absolute origin.
 *
 * @example
 * buildHreflangAlternates({
 *   slugs: { pl: 'o-nas', en: 'about' },
 *   config,
 *   baseUrl: 'https://example.com',
 * })
 * // → { pl: 'https://example.com/pl/o-nas', en: 'https://example.com/en/about' }
