• This end-to-end test case uses Co-authored-by: Cursor ..., so it will be removed by AI_NAMES_PATTERN even if the updated AI_EMAIL_PATTERN fails to recognize non-angle-bracket emails. To cover the intended regex expansion, add an additional E2E case where the name is not an AI tool but the email domain matches (e.g., Co-authored-by: Someone cursoragent@cursor.com).

    It 'removes Cursor co-author without angle brackets' {
        $content = "Fix bug`n`nCo-authored-by: Cursor cursoragent@cursor.com`n"
        $result = Invoke-BashHook $content
        $result | Should -Not -Match 'cursoragent@cursor\.com'
        $result.Trim() | Should -Be 'Fix bug'
    }
