Fix vLLM nightly wheel index URL

Changed from:
[[tool.uv.index]]
name = "vllm-nightly"
url = "https://wheels.vllm.ai"

To:
[[tool.uv.index]]
url = "https://wheels.vllm.ai/nightly"

- Removed unnecessary 'name' field (simpler syntax per UV docs)
- Fixed URL to use /nightly path for nightly builds
- Should now properly install pre-built wheels instead of building from source
