Code Review

This pull request adds a new Mergify rule to automatically label NVIDIA-related pull requests. The rule is well-structured, but the conditions could be expanded to be more comprehensive. I've suggested adding more keywords related to NVIDIA technologies like flashinfer, trtllm, nvml, and nvlink to both file path and title checks. This will improve the accuracy of the automation.

The conditions for applying the nvidia label are a good start, but could be more comprehensive. To improve the rule's accuracy, I suggest expanding the conditions to include other relevant NVIDIA-related keywords that appear in the codebase.

Specifically:

• flashinfer and trtllm are included for file paths but are missing from the title match.
• nvml and nvlink are other NVIDIA technologies used in the project and would be beneficial to include in both file and title matches.

This change will help ensure that more relevant PRs are correctly labeled.
