CI fix + Drawbar-stack deploy pattern

Browse Source 
CI was failing on the "Rebuild indexes from committed corpus" step
with httpx.ConnectError [Errno 111] — `localhost:11434` in the
OLLAMA_URL pool resolves to the Gitea Actions runner CONTAINER's
own localhost (no Ollama there), not the host. Fix: drop localhost
from CI's pool; it stays useful for dev runs from the workstation
where the TITAN X serves Ollama on the host loopback.

Final CI pool — 3 LAN endpoints, weighted to .0.125 (4090):
  .0.125:11434  ×4 (RTX 40-series, 242 embeds/sec)
  .0.2:11436    ×2 (GPU-pinned,    108 embeds/sec)
  .0.2:11435    ×1 (GPU-pinned,     72 embeds/sec)

deploy/docker-compose.yml — rewrite to match Drawbar's actual
parent-stack pattern, learned by inspecting how chem-mcp is
deployed on trashpanda:

  - Service name `seed-mcp` (matches chem-mcp's pattern). Reached
    via docker DNS as `seed-mcp:8080` from drawbar-backend-api.
  - Internal-only (no host port), expose 8080 only.
  - MCP_PORT=8080 inside container (chem-mcp uses 8080 too).
  - OLLAMA_URL via host.docker.internal:11434 (trashpanda's Ollama
    runs on the host). extra_hosts maps host-gateway.
  - RERANK_URL: http://llama-rerank:8080 — but llama-rerank is on
    the default `bridge` network, not drawbar-backend_default,
    so chem-mcp's reranker silently fails! Documented patch:
       docker network connect drawbar-backend_default llama-rerank
    Fixes rerank for BOTH chem-mcp (today: dense-only fallback)
    and the new seed-mcp.
  - Watchtower label set so CI pushes to :latest auto-deploy.

Documented llama-rerank service block as an alternative for
bringing the sidecar fully into the parent compose stack, with the
ubatch-size flag the seed corpus needs.
