The direct cast of Error to Record<string, unknown> is rejected by
TypeScript because the types don't sufficiently overlap. Cast via
unknown first to satisfy the compiler.

viem's BaseError extends Error, so the instanceof Error branch was
firing and returning error.message before the isRecord branch could
check shortMessage. Check shortMessage first inside instanceof Error
so terse viem messages are shown to users instead of verbose full ones.
