Author docker-compose stack: llama.cpp (ROCm) + Open WebUI + Qdrant + Lazytainer

Resolves wayfinder ticket #4. Wires up the locked decisions from the map:
- llama.cpp (ghcr.io/ggml-org/llama.cpp:server-rocm, gfx1201) serving
  Qwen3.8-27B-UD-Q4_K_XL.gguf, port published for direct Claude Code CLI /
  Kimi CLI access alongside Open WebUI.
- Open WebUI with WEBUI_AUTH on, RAG+Memory wired to a standalone Qdrant
  service.
- Lazytainer labels on llama-server for a 15 min idle-stop.
- Named Docker volumes only (models, qdrant-data, openwebui-data) — no host
  bind-mounts.
- One-off 'downloader' compose profile instead of a host-side script with
  its own dependencies, wrapped by scripts/download-model.sh.

+# LLM-Server
+
+Local AI inference stack: llama.cpp (ROCm) serving Qwen3.8-27B on an AMD Radeon AI PRO R9700, fronted by Open WebUI (RAG + Memory via Qdrant), with Lazytainer auto-suspending the inference container when idle.
+
+See the wayfinder map ([issue #1](https://git.arthurerlich.de/haylan/LLM-Server/issues/1)) for the full architecture rationale and open questions.
+
+## Quickstart
+
+```bash
+cp .env.example .env      # adjust if needed
+./scripts/download-model.sh
+docker compose up -d
+```
+
+- Open WebUI: http://localhost:3000 (first signup becomes the admin account — `WEBUI_AUTH` is on)
+- llama.cpp OpenAI-compatible API: http://localhost:8080/v1
+- llama.cpp Anthropic Messages API (for Claude Code CLI): http://localhost:8080/v1/messages
+
+Pointing Claude Code CLI or Kimi CLI at the local endpoint is documented separately — see [issue #6](https://git.arthurerlich.de/haylan/LLM-Server/issues/6) once resolved.
+
+**Known risk**: Qwen3.8-27B's tool-calling reliability against llama.cpp's Anthropic shim is not yet verified (open upstream parser bugs against its model lineage) — see `docs/research/qwen3.8-27b-tool-calling.md`.
