The read handler now composes full directory paths from the cdir's directory ids rather than emitting bare leaf names: build_dir_path walks the parent chain (root dirid 0, depth-capped against cyclic cdirs), so multi-file archives with subdirectories list correctly. Master-block resolution (M4) and tagged long names (M6) already work through libuc2's extract and tag paths; this adds a libarchive round-trip test that creates archives at Huffman and rANS levels and verifies every byte back through libarchive's public API. Documents the plugin build recipe (libarchive source tree + static lib). Verified against libarchive 3.7.7; round-trip clean under valgrind.
