/**
 * Resolve `$ref` pointers in a remote tool's input schema before it is
 * converted.
 *
 * A `$ref` reached the converter's `default:` branch and became "anything":
 * no type, no shape, nothing for the model to work from. And because the
 * resulting node is inherently optional, a `$ref`'d field the server listed
 * as required stopped being enforced too — an empty payload validated
 * clean and was forwarded to the server instead of being rejected with the
 * "Required: <field>" hint the executor already knows how to build.
 *
 * That is not an exotic shape. `$defs` + `$ref` is what several widely used
 * schema generators emit by default for a nested object, so a server that
 * did everything right presented its main argument to the model as `{}`.
