Code Review

This pull request updates the .github/CODEOWNERS file to assign owners to the new megatron_utils and sglang_utils directories. No security vulnerabilities were found. A suggestion has been made to improve the long-term maintainability of the CODEOWNERS file by utilizing GitHub teams, which would help reduce duplication and simplify future updates.

While this is correct, repeating the list of owners @fzyzcjy @yueming-yuan @maocheng23 can become a maintenance burden if more directories are added or ownership changes.

For better long-term maintainability, consider using a GitHub team for this common set of owners. For example, you could create a team (e.g., @<org>/miles-backend-owners) for @fzyzcjy @yueming-yuan @maocheng23.

Then, these lines and others in the file could be simplified:

# In this PR
/miles/backends/megatron_utils/ @<org>/miles-backend-owners @yushengsu-thu
/miles/backends/sglang_utils/ @<org>/miles-backend-owners @yushengsu-thu

# Elsewhere in the file
/miles/backends/ @<org>/miles-backend-owners

This makes it easier to manage ownership changes in the future, as you'd only need to update the team membership in one place.
