refactor(archiver): yield PathBuf from ArchivableFilesFinder, drop SplFileInfo

Migrate ArchivableFilesFinder off Symfony's SplFileInfo onto Path/PathBuf,
resolving the phar_archiver TODO(phase-b) that required a .map() adapter to
bridge SplFileInfo -> PathBuf.

- ArchivableFilesFinder now yields PathBuf; accept() takes &Path; the exclude
  closure receives &Path and uses Path::canonicalize / is_symlink. The
  SplFileInfo -> PathBuf conversion happens once at the symfony get_iterator
  boundary (get_iterator stays SplFileInfo for cache.rs).
- symfony Finder::filter callback changed to FnMut(&Path) (sole caller is the
  finder).
- PharArchiver passes the finder straight into ArchivableFilesFilter, mirroring
  PHP's new ArchivableFilesFilter($files).
- ZipArchiver consumes PathBuf items, computing the relative path via
  strip_prefix(sources) in place of SplFileInfo::getRelativePathname.
