Introduces a single, idempotent baseline role to supersede the overlapping day0-baseline and common roles. Capabilities are feature-flagged so they can be toggled per-host: - packages (common + OS-family + per-host extras) - timezone + locale - chrony time sync against sundial - baseline users (jarvis admin account with SSH key + NOPASSWD sudo) - SSH hardening via /etc/ssh/sshd_config.d/ drop-in - unattended security upgrades (Debian family) - sysctl drop-in at /etc/sysctl.d/99-mk-labs.conf - journald retention caps - branded MOTD Ubuntu/Debian is first-class; vars/RedHat.yml provides a placeholder for future distros via the ansible_os_family pattern. The legacy day0-baseline and common roles remain in place for now and will be removed during the playbook cleanup sweep, alongside the existing playbook naming inconsistencies.
