feat: add Atlas Inference Engine provider detection (closes #674)

Add Atlas (pure Rust+CUDA inference engine by Avarok) to the provider
registry and local server detection.

Changes:
- agent/model_metadata.py:
  - _URL_TO_PROVIDER: add localhost:8888 -> atlas mapping
  - detect_local_server_type: add Atlas detection via /health endpoint
    (checks for engine=atlas in response) and /v1/models fallback
  - Update docstring to include atlas in return type

Atlas serves OpenAI-compatible API at localhost:8888/v1 from a 2.5 GB
Docker image. 3x faster than vLLM with zero Python dependencies.

Quick start:
  docker pull avarok/atlas-gb10:alpha-2.8
  docker run -d --gpus all --ipc=host -p 8888:8888 \
    -v ~/.cache/huggingface:/root/.cache/huggingface \
    avarok/atlas-gb10:alpha-2.8 serve \
    Sehyo/Qwen3.5-35B-A3B-NVFP4 --speculative

Hermes config (config.yaml):
  provider: custom
  base_url: http://localhost:8888/v1
