docs: migrate all documentation to Discourse wiki topics

All knowledge docs (architecture, runbooks, references, audits, policies)
have been migrated to community.turnsys.com as wiki topics in the VP
TechOps category. Discourse is now the canonical source of truth for
documentation; git edit history no longer serves as the doc changelog.

37 .md files converted to short pointers linking to their Discourse
topics. AGENTS.md updated with new documentation workflow policy.
Code (scripts, configs, playbooks) remains authoritative in git.

-> **Canonical naming policy for the PFVCluster fleet.**
-> Established: 2026-07-31
-
-## Rule
-
-**The Proxmox VM name is the canonical identifier.** Everything else
-derives from it:
-
-1. **VM name** (set via `qm set <vmid> --name <name>`) is the source of truth
-2. **DNS records** (Technitium, forward + reverse) must match the VM name exactly
-3. **Tailscale node name** must match the VM name
-4. **Monitoring/alerting** (Beszel, Uptime Kuma, LibreNMS) uses the VM name
-5. **Inventory/k8s** references use the VM name
-
-Any mismatch between VM name and DNS/Tailscale name is a **critical bug**
-that must be fixed. The Technitium DNS API key is stored at
-`~/.secrets/api-keys.env` for programmatic DNS management.

-## Tools
-
-- Technitium DNS API key: `~/.secrets/api-keys.env`
-- Uptime Kuma API key: `~/.secrets/api-keys.env`
-- DNS audit: `perf/scripts/probe-vm-dns.sh`
