/**
 * Free-text location → URL slug (cohort candidate G).
 *
 * The cohort portals whose search routes take a slug segment
 * (`/homes-for-sale/<slug>/`) all slugify a free-text location the same
 * way: NFKD-normalize, strip diacritics, lowercase, collapse runs of
 * non-alphanumerics to a single `-`, then trim leading/trailing `-`.
 *
 * This was byte-identical in `compass-mcp/src/url.ts` and
 * `homes-mcp/src/url.ts`; the canonical version hoists it verbatim.
 *
 * Pure / dependency-free.
