Restores the kernel-level isolation the pre-cutover ttyd-session.sh had, but keeps the multi-session lobby UX: - ttyd.service gets `-H X-authentik-username` back. `tmux-attach.sh` reads $TTYD_USER, looks up the local part in /etc/ttyd-user-map, denies the connection (no fallback to wizard) if there's no mapping, otherwise `sudo -n -H -u <os_user> tmux …`. Each Authentik identity → its own Unix user → its own `/tmp/tmux-<uid>/default` socket. - tmux-api scopes every request to the same OS user via the same header. Adds /whoami so the lobby HTML can preflight access and render "logged in as <os_user> (<authentik>)" instead of leaving the user to discover the deny via a reconnect loop. - Commits /etc/ttyd-user-map and the matching /etc/sudoers.d/ttyd-users fragment under files/devvm/ so future operators see one canonical source of truth. Current mappings: vbarzin → wizard, emil.barzin → emo. Adding a user is now: append a line to ttyd-user-map + a NOPASSWD sudoers line + `useradd -m`. README walks through it. No Terraform changes — this is all DevVM-side + lobby JS.
