feat: Day 9 — Docker deployment with Dockerfile and docker-compose

- Dockerfile: python:3.11-slim, copies source before pip install,
pre-downloads embedding model and runs ingestion at build time
- docker-compose.yaml: maps port 8000, passes OPENAI_API_KEY,
mounts .cache volume for embedding persistence
- .dockerignore: excludes tests, docs, .git, caches from build context

Docker daemon not running in this environment — build not verified.
Dockerfile follows design spec exactly (copy-before-install pattern).
