1. 1. Summary

Move platform quality checks out of required/nightly variants:

• Move macOS `bazel_run_format`, `bazel_run_lint`, and `bazel_run_codeowners` from nightly `enterprise-macos` to master-only `enterprise-macos-arm64`.
• Move Windows `bazel_run_format` and `bazel_run_lint` from required `windows-compile-required` to non-required `windows-compile-suggested`.
• Remove the platform-specific entries from `github_pr_aliases` and `commit_queue_aliases`, so these tasks are not selected by PR or commit-queue checks.
• Update `validate_evg_project_config.main` to validate shared task definitions against both master and nightly configurations.

This preserves the existing task definitions and commands while keeping platform quality coverage on development variants and avoiding platform-specific PR/required validation failures. No server or runtime behavior changes are involved.

1. 1. Testing

• `bazel run format`
• `bazel run --config=local buildscripts:yamllinters` — both Evergreen configs passed
• Focused Evergreen validator test — 7 tests passed
• `git diff --check`
• Required patch 6789 verified with no Windows or macOS quality tasks selected
