DerLinkman 30f3e9a4c6 rename dmc12 inventory to cloudlorean and vault admin_password

- replace inventory/dmc12.yml with cloudlorean.yml (+ group_vars) and update
  all README/AGENTS call examples and the inventory table
- move admin_password hash into encrypted vault.yml; remove plaintext copies
  from roles/bootstrap/defaults and group_vars/external.yml
- bootstrap.yml loads vault.yml via vars_files (same pattern as monitoring)
- monitoring: PSK config/registration updates, docker role defaults,
  os-updates logging/reboot refinements, ansible.cfg/execute.sh tweaks
- add .project-wiki knowledge base and .github agent instructions

Project Overview

Name

ansible-playbooks - central Ansible collection for Debian host management.

Goal

Provide a single, reusable Ansible repository to provision, harden, update, and monitor Debian hosts in a consistent, documented, and repeatable way.

Domain

Infrastructure automation and IT operations:

Target hosts are Debian systems, partially running as LXC containers on Proxmox.
Execution happens in a controlled Docker runtime environment (execute.sh, docker/).
Secrets are managed via Ansible Vault (vault.yml, git-ignored .vault_pass).

Roles (building blocks)

Role	Purpose
`bootstrap`	Initial setup: packages, admin user, SSH, MOTD, sysctl, Docker, monitoring
`docker`	Docker Engine installation from the official repository
`hawser`	Update of the Hawser Docker Compose stack
`healthcheck`	Quality gate: verify running containers after updates
`manage-ssh-keys`	SSH key management (hardening)
`monitoring`	Zabbix Agent 2: installation, TLS-PSK, Docker plugin, API registration
`os-updates`	Debian package updates with mirror switch, reboot, and logging

Constraints

See Constraints. Key points: Debian-only playbooks, LXC-aware skips for sysctl/reboot, mandatory documentation of every change, FQCN module usage, secrets never committed in plain text.

Stakeholders

Not explicitly documented yet. See STATUS.md open questions.
