W-040 Status

status: in_progress task: 固定 OPFS 目录布局

web/app/src/storage/opfs-files.ts validates project IDs and file names, creates projects/<id>/scene.blend, snapshots/, assets/, thumbs/ and tmp/, and writes a complete scene buffer through a temporary file before replacement. The standard FileSystemHandle.move path is used when available; the copy-and-remove fallback is bounded to the same project directory.

Large asset hashing, crash-recovery manifests and cross-browser atomic rename guarantees remain subsequent tasks.
