+ * GitHub Action script for managing issue backlog.
+ * 
+ * Behavior:
+ * - Pull Requests are skipped (only opened issues are processed)
+ * - Skips issues with 'to-be-discussed' label.
+ * - Closes issues with label 'awaiting-response' or without assignees, 
+ *   with a standard closure comment.
+ * - Sends a Friendly Reminder comment to assigned issues without 
+ *   exempt labels that have been inactive for 90+ days.
+ * - Avoids sending duplicate Friendly Reminder comments if one was 
+ *   posted within the last 7 days.
+ * - Moves issues labeled 'questions' to GitHub Discussions
