/**
 * Channel-aware contact autosuggest (design: contact-model-three-layer.md Phase 7). Replaces the
 * misuse of useContacts()/listContacts({limit:1000}) as an autosuggest source: this hits the
 * dedicated per-user, deduped-by-person crm.suggestContacts endpoint and returns only what an
 * autosuggest needs. The result is adapted to the `{ person: { email, name, currentRole } }` shape
 * the existing autosuggest components consume, so callers swap one hook and nothing else.
 *
 * @param channel - which address book to draw from (email | whatsapp | linkedin). Default: email.
 * @param enabled - lazy-load switch (default true).
