perf: Simplify JSON-RPC failure validation

[FrederikBolding]

Swap JSON-RPC failure validation to a faster implementation since we control the responses we know that the error is valid.

---

Note

Replace JSON-RPC failure detection with a direct error property check in AbstractExecutionService.#command, updating related imports/types.
