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

+# Analysis
+
+This section stores durable, non-canonical synthesis produced from meaningful project questions or agent analysis. Prefer updating canonical docs when the information clearly belongs in requirements, changes, ADRs, technical docs, implementation docs, or traceability maps.
+
+## When To Read
+
+- Review stable tradeoff analyses, impact maps, or exploratory syntheses.
+- Understand connections across requirements, changes, decisions, technical docs, alerts, and source paths.
+
+## Rules
+
+- Do not create isolated analysis pages.
+- Every analysis page must link to related wiki records or source paths.
+- Do not store routine chat answers, generic explanations, transient debugging notes, or duplicated content here.
+
+## Analysis Pages
