What

Trac ticket: #65819

Makes the data providers in tests/phpunit/tests/file.php static.

Why

PHPUnit data providers should be static so they do not depend on test instance state and remain compatible with current PHPUnit usage in Core.

How

• Convert data_wp_tempnam_filenames() to public static
• Convert data_wp_tempnam_should_limit_filename_length_to_252_characters() to public static

Test-only; no production code changes.

Testing Instructions

1. npm run test:php -- --filter Tests_File
2. npm run test:php -- --filter Tests_File -c tests/phpunit/multisite.xml
3. npm run test:php -- --filter Tests_File --order-by=random
4. npm run test:php -- --group file
