Subject: [PATCH 3/4] Revert "Use macos-13 instead of macos-latest for faster
 CI builds"

The issue is not Rosetta 2 emulation overhead. Investigation shows the build is stalling/hanging with orphaned Node.js processes on GitHub's macOS runners, which requires different diagnosis.

Subject: [PATCH 4/4] Add process monitoring diagnostics for macOS CI builds

Adds background process monitoring that runs ps every 30 seconds during the build on macOS to diagnose hanging issues. The monitor tracks node/tsc/lerna processes and logs output, which is displayed at the end of the job to help identify when and where processes get orphaned.
