Pull request overview
This PR optimizes the CI workflow by reducing macOS builds to conserve limited GitHub Actions resources. It ensures macOS is only tested on the oldest and newest Node versions (16 and 24) and completely disables macOS in PR CI while still running it on direct pushes to main/release branches.
Changes:
- Added skip conditions to disable macOS builds during pull requests and merge queue events
- Removed previously commented-out macOS configurations for Node versions 18, 20, and 22
- Updated comments to clarify that PRs only test the newest and oldest Node versions, and macOS is never checked in PRs

These builders are often MIA. Turn them off in PR CI. And, stop testing macOS except for the oldest/newest versions.
