/**
 * #2463 — parseModel must not crash on a non-string truthy input.
 *
 * The NVIDIA NIM investigation (Part C) showed parseModel({}) threw
 * `cleanStr.endsWith is not a function`: the `if (!modelStr)` guard only catches
 * falsy values (null/undefined/""), so a truthy non-string (object/number/array
 * — e.g. a malformed combo `modelStr` or providerSpecificData saved as an object
 * by a UI bug) reached `cleanStr.endsWith("[1m]")` and crashed. Same class of bug
 * as #2359 (combo modelStr) and the proxyFetch errCode crash.
