Opt-in overlays under docker/ that pass the host GPU into the odysseus
container. Pick one in .env:
COMPOSE_FILE=docker-compose.yml:docker/gpu.nvidia.yml
COMPOSE_FILE=docker-compose.yml:docker/gpu.amd.yml
Non-GPU users are unaffected (no default merge). README now points at
the overlays instead of the old ad-hoc `gpus: all` suggestion.
Each overlay header notes that it only exposes the GPU devices — the
slim image still needs vLLM / llama-cpp-python / etc. installed via
Cookbook -> Dependencies before models can serve on GPU.
Tested on Arch + Docker 29.5.1 + RTX 4090:
docker compose exec odysseus nvidia-smi -L
GPU 0: NVIDIA GeForce RTX 4090 (UUID: GPU-...)
Cookbook hardware scan reports the 24 GB GPU and recommends GPU-fit
models. `docker compose config` validates cleanly for all three
COMPOSE_FILE variants (base, +nvidia, +amd).
Builds on the structure proposed in #91 by @krllus with the path /
docs fixes from the review on that PR.
Closes#163.
