[bendhouseart]

A nested/derivatives bids dataset returns a 0 exit code even if it's evaluated as invalid, this PR sets the exit code to non-zero in that case.

What about a simple boolean function to find the first error and stop?

Here's a quick function I haven't tested:

export function detectErrors(result: ValidationResult): boolean {
  return result.issues.get({ severity: 'error' }).length > 0 ||
    Object.values(result.derivativesSummary ?? {}).some((res) => detectErrors(res))
}

I like where your head's at.
