/**
* GET /api/plants/suggestions?q=<term>
*
* Returns autocomplete suggestions for the navbar search-as-you-type feature.
* Queries both plants and diseases from the database and returns an interleaved
* list with at most 8 suggestions total.
*
* Each suggestion includes: type (plant|disease), id, label, subtitle, emoji, href.
* Plants link to their browse detail page; diseases link to the plant page with
* a hash anchor to the specific disease card.
