docs: one knowledge base for both workloads

- docs/index.md: LLM Fleet section (all 34 pages linked), merge note,
  See Also now internal
- docs/LLM/index.md: retitled, dangling [[Dankserver]]/[[Dankclaw]]
  links fixed, sibling section replaced with internal links
- docs/LLM/deployment.md: rewritten for the unified deploy flow,
  manual-update paths point at the merged checkout, incident history
  kept intact
- Deployment Flow / Dankclaw Stack / Gitea: stale vllmScripts
  references and retired-topology notes updated to the 2026-08-22
  state
- Historical docs (frank-redo, PP deployment, FastFlowLM) keep their
  dated runbook paths as-is (records of retired topologies)

 - **The files in the data directory are owned by host UID 100999**, not `dank` (rootless ID mapping: container uid 1000 → host 100999). Edit them inside the container with `podman exec --user 1000 gitea-server ...`.
 - **The host auto-reboots.** `unattended-upgrades` reboots Dankclaw when a package needs it. The quadlet units make Gitea survive that. See the 2026-08-16 incident below.
 - **Port 3000 vs 3001.** The live host port is 3000. The full-stack [`dankclaw/compose.yaml`](../compose.yaml) maps 3001. Align the two before deploying the full stack.
-- **Legacy compose retired.** `/opt/gitea/podman-compose.yml` is retired to `/opt/gitea/.deprecated/`. Do not run it; its containers would collide with the quadlet units on ports 3000, 2222, 80, and 443.

 - **Rootless cannot bind ports below 1024 by default.** `gitea-caddy` publishes 80 and 443. Without a host sysctl, `rootlessport` fails with `permission denied` and the unit crash-loops under `Restart=always`. The fix is a one-time sysctl: `net.ipv4.ip_unprivileged_port_start=80`, persisted in `/etc/sysctl.d/99-rootless-ports.conf`. Applied 2026-08-18 after a 13,000-restart crash loop.
