Preserve passwords from server-info.yml and vault; generate only for new users; remove deleted users from output; re-export URL/QR only when password, domain, port, obfs or files changed.
Remove binary, config, masq, system user, ufw rules, and apt packages from VPS; delete output/<server>/ by default and rebuild global index.html via localhost play.
Use Ansible password lookup on the control node so install works before packages are installed on VPS and without pwgen on macOS. Export EDITOR=nano in Makefile for vault-edit.
