 * - MCP `tools/call` failures, marked `isError` at the protocol boundary;
 * - `run_sdk` script failures, reported as data (`success` is a required
 *   field of the script result) — the tool ran fine, the script did not;
 * - REST-proxy soft failures, a top-level `error` string. This mirrors the
 *   server's `isSoftErrorResult` (server/src/tools/execute.ts); kept as a
 *   local predicate so the CLI never imports server sources.
