feat(ansible): add swapfile + resource_limits roles; add CoulombCore to inventory T01: roles/swapfile — idempotent 4GB swapfile, vm.swappiness=10, fstab entry T02: roles/resource_limits — PAM nproc caps (512/1024), systemd user-1000.slice memory limits (1500M/512M); templated per-host via host_vars - inventory/host_vars/CoulombCore.yml — host-specific vars for both roles - inventory/servers.yaml — add CoulombCore with id_ops SSH key - inventory_from_yaml.py — load host_vars files into Ansible hostvars - playbooks/bootstrap.yaml — include swapfile + resource_limits roles - workplans/WP-0004 — flag T04/T09/T10 needs_human, add CoulombCore-local convergence note Codifies manual INC-002 hardening.
