docs: cross-link the vllmScripts project (model endpoints + git host)

- README: fix broken 'Also See' placeholder URL -> live Gitea LAN URL
- index.md: expand vllmScripts See Also with the endpoints it serves
- OpenWebUI.md: :7770 backend is the llama.cpp PP head (split to the
  3090), managed by vllmScripts; note the FLM NPU :52625 alternative;
  fix the broken [[llama.cpp Server]] wikilink
- Gitea.md: hosted repositories table (both projects)
- Dankclaw Stack.md: host-level LLM endpoints in the service inventory
- AGENTS.md: runtime note — LLM endpoints live in vllmScripts, not here

Pre-existing failures (untracked ComfyUI WIP): tests 6, 8, 9, 10.
Docs seams green: ok 19 (compose service docs), ok 20 (index links).

 ## Runtime & Troubleshooting
 
+- The LLM endpoints are bare-metal systemd services managed by the sibling `vllmScripts` repository (`../vllmScripts`), not by this repo: llama.cpp PP head `:7770` and FastFlowLM NPU `:52625` on Dankclaw, RPC worker `:50052` on Dankserver. Do not edit their scripts here.
 - Model load on the LLM servers takes 3–8 minutes; `503 Loading model` is normal during load. Do not kill the process.
 - `sudo` on both boxes needs a tty. Do not use `echo password | sudo -S` in committed scripts; run sudo interactively.
 - Never run `pkill -f` with a pattern that appears in your own command line. Use `pkill -x <exact-name>`.
