- config/git/gitconfig: real name, email, and SSH signing key - config/shell/zshrc: fix typo 'powerlevel10zsh' → 'powerlevel10k' - config/systemd/bw-ssh-keys.service: depend on graphical-session instead of network (ssh-agent starts with session); add explicit PATH so bw and jq are found; add RemainAfterExit=yes (avoids restart loop on oneshot services)
