/**
 * Submit User Data Router
 *
 * tRPC router for submitting user data (name, email) with file attachment references.
 * Files should first be uploaded via /api/upload, then referenced here.
 *
 * In a real app, you'd use qb.uploadAttachments() to store files in TaylorDB
 * and insert the record with the attachment column. This demo uses in-memory storage.
 *
 * TaylorDB attachment pattern (see docs/TAYLORDB_ATTACHMENTS.md):
 *   await qb.insertInto("users").values({
 *     name: "Jane",
 *     avatar: await qb.uploadAttachments([
 *       { file: new Blob([buffer]), name: "photo.png" },
 *     ]),
 *   }).execute();
