Replace 'rsync -az' with 'rsync -rlptDz' (archive minus owner/group
preservation). Running as a non-root user on the VM, rsync can't
preserve UID anyway, but it was successfully preserving GID whenever
the numeric GID happened to exist on the target. That caused synced
dirs (~/.aws, ~/.config/opencode, ~/.config/nvim, ~/.agents/skills,
~/.ssh) to end up with group 1001 on the VM, which was confusing
and, for group-writable mode, potentially insecure.
With -o and -g dropped, received files get the receiving user's
UID:GID (devbox:devbox), which is what you want.
