Use Symfony Finder for file discovery. getAvailablePaths() manually composes recursive iterators and filters entries, contrary to the repository guideline. Replace this traversal with Symfony Finder while preserving symlink following and relative-path output.

Fixes wintercms/winter#1533 (filed there since issues are disabled on this repo).
FileDatasource::getAvailablePaths()builds itsRecursiveDirectoryIteratorwithoutFOLLOW_SYMLINKS, soRecursiveDirectoryIterator::hasChildren()treats a symlinked directory as a leaf and everything beneath it is skipped. This breaks zero-downtime deploy layouts (Forge/Envoyer-style) where a theme'scontent/metadirectories are symlinks into a shared folder — a child theme (anything withparent:intheme.yaml) resolves throughAutoDatasource, which feeds off this method, so it sees no static pages at all and every Pages URL 404s. Parent themes are unaffected becauseselect()/selectOne()open the target path directly rather than walking through it, so the bug only shows up on the auto-datasource path-cache side.Added the flag (keeping the two default flags explicit alongside it, since passing any explicit flags value overrides the constructor's defaults) and a regression test with a real symlinked directory. Left
select()'s own iterator as-is — giving it the same flag surfaces a separate, pre-existing path-validation check (makeDirectoryPath()'s "must resolve within basePath" guard) that legitimately rejects reads through a symlink, so fixing that would be a different, bigger change than this issue asks for.Ran the full
FileDatasourceTestsuite plus phpcs against the changed files.Used AI assistance (Claude) to investigate and write this fix.
