/**
 * Adds a redirect path to a document
 *
 * This function creates a new route that points to an existing document,
 * creating a redirect from the specified path to the document's canonical path.
 *
 * The path must not already exist in the routes table (enforced by unique constraint).
 * The path must follow routing rules (no leading/trailing underscores, etc.)
 *
 * @param client Database client
 * @param query Document query (supports path string, id number, OptimisticDocument, Route, etc.)
 * @param input Object containing the redirect path
 * @returns The newly created Route object
 * @throws Error if document doesn't exist or path already exists
