The viewer can now open a .rdb directory (as produced by RocksDbSerializer / convert_path_to_rocksdb) anywhere it accepts an .ifc file. The full GUI gets an "Add Database..." File menu entry that opens a directory chooser; the streamer lets the file constructor autodetect the format and opens the store read-only so multiple viewers can share a database without taking the exclusive RocksDB lock. Parallel mapping on RocksDB-backed files still produces non-deterministic shape counts (the race is outside the instance cache), so force num_threads=1 for the iterator when the storage is RocksDB. Serial RocksDB (~2.6s) and parallel SPF (~0.7s) both produce 107 shapes on AC20-FZK-Haus; @todo in-source points at the remaining thread-safety work.
