* fix(core): guard material-ref parsers against non-string values (Sentry MONOREPO-EDITOR-EM) getLibraryMaterialIdFromRef and getSceneMaterialIdFromRef only guarded against null/undefined, then called .startsWith(). When a non-string material ref reaches them (legacy/malformed wall material slot ref), .startsWith is undefined -> TypeError: e.startsWith is not a function. Narrow with typeof !== 'string' -> return null, so a bad ref degrades to 'no library/scene material' instead of throwing during wall material resolution (packages/viewer wall-materials.ts -> parseMaterialRef). * test(core): cover malformed material refs --------- Co-authored-by: Aymeric Rabot <aymeric.rabot@gmail.com>
