auto-claude: subtask-3-4 - Run all tests and verify they pass

Fixed bug in social media exclusion logic that was too aggressive.
The substring check `any(ex in match.lower() for ex in excludes)`
was incorrectly excluding valid usernames containing exclusion
strings (e.g., 'testcompany' was excluded because it contained 'p').

Changed to exact match only to properly handle Instagram post URLs
(`instagram.com/p/...`) without false positives on valid usernames.
