212 PHPCS formatting errors auto-fixed by phpcbf across 18 files.
All remaining issues are warnings (exit 2), not errors — CI treats
exit 2 as success via the same pattern as peptide-news-plugin.
Also adds class-psa-ai-content.php and class-psa-directory-api.php to
tests/bootstrap.php require list — both files exist in includes/ but
were missing from bootstrap, causing 5 PHPUnit "Class not found"
failures in AIGeneratorTest and DirectoryTest.
REST endpoint registration, compounds query, and compound formatting
moved to PSA_Directory_API. PSA_Directory retains shortcode rendering,
constants, and hook registration. Backward-compatible proxies.
