Upload no longer errors on restrictive filesystems
If you've ever tried to upload a book and gotten a confusing [Errno 1] Operation not permitted error — even though the book seemed to actually be in your library — this is the fix. It happens on filesystems that don't let the running user change file modes: CIFS shares without explicit file_mode/dir_mode, LinuxServer-style PUID/PGID Docker bind mounts, NFS squash-root shares. The data copy succeeded, but the follow-up "preserve permissions" step blew up and the error surfaced as if the whole upload had failed.
After this release, the permissions step is best-effort. If your filesystem allows it, modes are preserved; if it doesn't, the file is still uploaded successfully — you just get default permissions on the destination, which is fine because the ingest pipeline will re-process the file anyway.
