Subject: [PATCH] # Actions Cost Reduction: CI Matrix Optimization

This PR focuses on reducing GitHub Actions costs by optimizing the CI test matrix.

### Summary of Changes

1.  **CI Matrix Optimization**: Reduced the `test_mac` matrix in `Testing: CI` to only run on Node.js 20.x. Node.js 22.x and 24.x are still covered by the `test_linux` matrix.
    - **Reason**: macOS runners (especially `macos-latest-large`) are significantly more expensive than Linux runners.
    - **Impact**: Expected to reduce Mac runner usage by approximately 66% in the CI pipeline, leading to a significant reduction in overall Actions spend.

Other workflow optimizations previously included in this PR (Pulse and Brain) have been reverted to keep the scope focused on CI matrix changes.
