fix: repair broken redirect retry counter in link preview

[ValyKay]

Summary

• retries was declared as const, so it could never be incremented
• The increment expression retries + 1 was a no-op (evaluates and discards the result instead of assigning)
• This meant the retries >= maxRetry guard in handleRedirects could never trigger, allowing unbounded same-host redirects

Fix

• const retries = 0 → let retries = 0
• retries + 1 → retries += 1

Test plan

• Send a WhatsApp message containing a URL that triggers same-host redirects
• Verify redirects are now capped at 5 (maxRetry)
• Verify link previews still generate correctly for non-redirecting URLs

Summary by CodeRabbit

• Bug Fixes
  • Fixed redirect retry logic for link preview handling to properly enforce maximum retry limits.
