chore: bump version to 0.0.78 [skip ci]

When adding or editing a cloud sync path, append the last segment of the
remote directory to the local output directory (e.g. /home/ubuntu/strm + 电影).
Remote changes replace the previous auto-appended tail; local browse and blur
commit the base path with the current remote tail.
