 * validates `version` against `0 | 'legacy'` and THROWS on 1 even when the request
 * raised the ceiling, so a real `Connection` (which exposes `rpcEndpoint`) is read
 * as raw JSON-RPC instead. An injected double without an endpoint goes through its
 * own `getTransaction` with the ceiling raised. Returns the RPC `result` (null when
 * the signature is unknown); RPC and transport failures throw so callers keep
 * treating a failed lookup as inconclusive rather than as absence.
