rate_limited error handling

[wilsonNg007]

How is rate_limited error being surfaced to the RunPromptResult returned from runPrompt?

Does RunPromptResult .error.message contains "rate_limited"?

From @pelikhan:
It contains the error that vscode returns so that might be lost.

You should see a 429 error code. Genaiscript should automatically retry.
