Bug: Sort/filter mismatch in auto-close-duplicates script causes missed issues

Description

In scripts/auto-close-duplicates.ts (lines 123-141), there is a mismatch between how issues are paginated and how they are filtered:

• Issues are fetched from the API without specifying a sort parameter (defaults to sorting by updated time)
• But the filtering logic checks created_at <= threeDaysAgo

This mismatch means:

• An issue created 10 days ago but updated 1 hour ago will appear early in pagination
• An issue created 2 days ago but not updated recently may not appear until later pages
• This can cause the script to miss issues that should be processed or process them inefficiently

Expected Behavior

The sort parameter and the filter condition should be aligned — either:

• Sort by created time explicitly and filter by created_at, or
• Sort by updated time and filter by updated_at

Suggested Fix

Add sort=created to the API request to align with the created_at filter logic.
