Show numeric fiber ID when @c label is unresolved in find results.

   Components deep in the tree (e.g., 3000+ components in a React
   Native app) don't get @c labels assigned because getTree() traversal
   stops early. find returns @c? which can't be used with get-component.

Fix: output @c?(id:667) so users can pass the numeric ID directly.
