refactor: Enable workspace auto-entry with full sudo and skip permissions

- Restore workspace auto-entry on ai user login
- Use systemd-nspawn -q -D to enter workspace
- Start claude with --dangerously-skip-permissions (no approval needed)
- Grant wheel group full sudo access (NOPASSWD: ALL) for container operation
- ai user can perform all root operations via sudo in workspace
