Pull Request Overview

Clears AttemptStateMap after successful Atlas sign-in and Generative AI opt-in to prevent stale attempt state from persisting, and (possibly unintentionally) makes getAttempt internal by removing its export.

• Add AttemptStateMap.clear() after successful sign-in flow
• Add AttemptStateMap.clear() after successful opt-in flow
• Removed export from getAttempt, changing its visibility (potential API change)

[nitpick] Removing the export from getAttempt changes it from a public to a module-private function, which may break existing imports if it was used elsewhere. If this was intentional, document the change or update callers; if unintentional, restore the export keyword.

Suggested change

	function getAttempt(id?: number | null): AttemptState {
	export function getAttempt(id?: number | null): AttemptState {
