 * One list of rows, whatever shape the call site had.
 *
 * `Select` accepts three spellings of the same thing and they all have to arrive at the engine as
 * ONE flat array, or every feature downstream (filtering, `maxCount`, the hidden `<option>` list)
 * would need to know about all three:
 *
 *   • this library's flat rows, `{ value, label, group? }`
 *   • antd's nested groups, `{ label, options: [...] }`
 *   • a foreign row read through `fieldNames`, `{ id, name, children }`
 *
 * Written once, here, rather than in both `select.tsx` and `search-select.tsx` — the two branches
 * of one component must not disagree about what an option is. Group headings survive as the flat
 * `group` string the rows already carried, so a grouped list renders identically whichever
 * spelling produced it.
