docs: move narrative wiki under knowledge/wiki/ (phase 3)

Problem: node and cross-cutting narratives lived at the repo root
(containers/, vms/, infrastructure/, host .md files), interleaved with the
machine-readable substrate.

Change:
- Move containers/ -> knowledge/wiki/containers/, vms/ -> knowledge/wiki/vms/,
  infrastructure/ -> knowledge/wiki/infrastructure/, hosts/{hubris,strong}.md ->
  knowledge/wiki/hosts/, infrastructure/references/ -> knowledge/sources/references/,
  GLOSSARY.md -> knowledge/GLOSSARY.md.
- Add knowledge/{index.md,log.md,sources/index.md} scaffolding.
- Rewrite all relative links repo-wide via a path-resolving mapper (inbound +
  outbound + between-moved-files), including .hermes/, runbooks, operations,
  investigations, plans, README, AGENTS.
- Repoint inventory.yaml doc_page fields and regenerate hosts/*.yaml (which
  embed doc_page); update oikos/gen-topology.py output path, candidate doc
  paths, and footer links; update code-comment doc paths.

Substrate untouched in place: inventory.yaml, hosts/*.yaml (regenerated,
idempotent), oikos/ code, mcp/, secrets/, bin/.

Verification:
- Logical broken-link set identical to pre-move baseline (net 128 -> 127; the
  topology regen fixed one, introduced none). Remaining are pre-existing refs
  to destroyed/archived nodes, out of scope for this move.
- gen-topology.py --check exit 0 (in sync); cards carry knowledge/wiki/ doc paths.
- build_host_files.py idempotent; all inventory doc_page targets resolve.
- MCP contract verified: get_page/search_docs/get_changelog resolve moved pages.

+|------|---------|
+| **Authentik** | SSO/identity provider. Core runs on the VPS; forward-auth outpost at LXC 106 on hubris |
+| **Caddy** | Reverse proxy (LXC 121). Terminates TLS for every `*.hubris.network` hostname |
+| **Caveman** | Terse communication standard for agent responses — no filler, keep substance |
+| **Forward-auth** | Caddy snippet that delegates authentication to an Authentik outpost. Protects web UIs like qBit, SABnzbd |
+| **Gitea** | Git server at `git.hubris.network`. Hosts all tracked config repos |
+| **Gluetun** | WireGuard VPN sidecar on arriman. All \*arr traffic routes through it |
+| **HAOS** | Home Assistant Operating System. VM 108 on hubris |
+| **Hubris** | Primary Proxmox VE node (GMKtec NucBox M6 Ultra). PVE hostname, cluster member 1 |
+| **LXC** | Linux Container (Proxmox). VM-like isolation without a full OS kernel |
+| **LVM-thin** | Thin-provisioned logical volume manager. Used for all container/VM storage |
+| **MCP** | Model Context Protocol (MCP server at `mcp.hubris.network`). Structured tools for agents to query homelab state |
+| **Mesh** | Overlay VPN for off-LAN connectivity. Netbird is current; Tailscale is legacy |
+| **Netbird** | Preferred mesh VPN. VPS hosts the management plane; all homelab nodes are members |
+| **OIDC** | OpenID Connect. Protocol used by Authentik for SSO login flows |
+| **Oikos** | Agent operating model ([.agents/OIKOS.md](../.agents/OIKOS.md)). OODA loop, risk classes, policy, ontology |
+| **PVE** | Proxmox Virtual Environment — the hypervisor on both hubris and strong |
+| **SOPS** | `sops` — Mozilla SOPS. Encrypts secrets with age keys so they live in the git repo |
+| **Strong** | Secondary Proxmox VE node. Cluster member 2 (hostname `strong`, nickname ludo/ludo-mini) |
+| **Traefik** | Reverse proxy on IONOS VPS. Serves `*.hubris.network` to the public internet |
+| **VAAPI** | Video Acceleration API. Intel/AMD GPU-based hardware transcode for Jellyfin |
+| **VPS** | Virtual Private Server at IONOS (`82.165.190.79`). Runs Authentik core + Netbird management |
+| **\\*arr** | Media automation suite: Sonarr (TV), Radarr (movies), Lidarr (music), Prowlarr (indexer), Bazarr (subtitles), Readarr (books — not in use) |
