~/Projects is a symlink to ~/Nextcloud/Projects — one directory, not two
clones. The differing user/main refs came from the worktree having its own
submodule git dir (.git/worktrees/<name>/modules/user), which is worth
knowing: submodule commits made from the main checkout stay invisible in a
worktree until fetched, and a local fetch moves them without a push.
