Auto-merge docs-only PRs / auto-merge-docs (pull_request) Successful in 5s

Pre-checks confirmed safe to right-size: no container --memory limits,
no Docker Compose memory reservations. Live usage 1.1 GB / 15 GB (7%).

- Update 106.conf: memory 16384 → 6144, sockets 2 → 1 (8 → 4 vCPUs)
- Add right-sizing-vm-106.md runbook with pre-check results and resize commands

Closes #19

7a0c264f27 feat: add monthly Proxmox maintenance reboot automation (#26) 
Establishes a first-Sunday-of-the-month maintenance window orchestrated
by Ansible on LXC 304. Split into two playbooks to handle the self-reboot
paradox (the controller is a guest on the host being rebooted):

- monthly-reboot.yml: snapshots, tiered shutdown with per-guest polling,
  fire-and-forget host reboot
- post-reboot-startup.yml: controlled tiered startup with staggered delays,
  Pi-hole UDP DNS fix, validation, and snapshot cleanup

Also fixes onboot:1 on VM 109, LXC 221, LXC 223 and creates a recurring
Google Calendar event for the maintenance window.

Closes #26
