projects-bind: bind anotherim back from /mnt/data

The root filesystem filled up, so ~/Code/projects/anotherim moved to
/mnt/data. Bind-mount it back to its old path so tools that refer to it
by path (Claude Code project memory, git worktrees, dev flakes) keep
working. /mnt/data is plain ext4, not LUKS; that tradeoff was accepted
for the move.
