alvis 1e66d3dcb5 openai: deploy cognee + cognee-mcp memory service [Adolf P4] ...

Resolves the 4 P4 blockers and wires cognee/cognee-mcp into the openai
compose stack:

- qdrant: container was gone (data intact under /mnt/ssd/dbs/qdrant);
  brought back up, confirmed healthy on :6333.
- Embeddings: switched from a dead LiteLLM route to ollama directly
  (host.docker.internal:11436, nomic-embed-text, 768-dim), using cognee's
  dedicated OllamaEmbeddingEngine and its native /api/embed endpoint.
  Requires extra_hosts: host.docker.internal:host-gateway since ollama
  lives in a separate compose project.
- cognee-llm kimi auth: root cause was that cognee-llm had never been
  started, so its kimi-agent-home-equivalent volume didn't exist yet.
  Seeded cognee-llm-home from the already-authed kimi-agent-home volume
  (read-only copy of config/credentials/oauth/device_id); cognee-llm now
  serves real completions.
- mkdir'd cognee data/system dirs: confirmed present (done by user).

Also fixed three issues found only during a live end-to-end smoke test:
- VECTOR_DB_PROVIDER must be a real container env var, not just present in
  the mounted cognee.env — the qdrant adapter's sitecustomize.py
  registration hook reads os.environ directly, which pydantic-settings'
  env_file parsing never populates.
- Baked the Kuzu/Ladybug JSON extension into the cognee image. This
  deployment's egress to extension.ladybugdb.com is bandwidth-throttled to
  ~1.2 KB/s, so cognee's own runtime auto-download reliably timed out,
  leaving /health permanently unhealthy and graph queries failing. Fetched
  the ~827KB extension out-of-band (16-way parallel ranged GETs) and added
  it to the image via COPY.
- LLM_ENDPOINT needed an explicit /v1 suffix (litellm appends
  "/chat/completions" verbatim) and LLM_INSTRUCTOR_MODE=json_mode is
  required since cognee-llm's Kimi wrapper is a text-only pass-through with
  no real tool-calling support.

Verified with a full remember -> recall round trip through cognee-mcp's
MCP tool surface: stored a fact containing a codeword, recalled it via
GRAPH_COMPLETION search, got the exact codeword back. Exercises cognee-llm,
ollama embeddings, Qdrant, and Kuzu together.
