This extends the CI policy from #8600 to macOS: PRs now run Ubuntu-only
for the affected CI lanes, while macOS and Windows remain enabled on
`main`.

- **Cargo test matrix**
  - Make the `cargo-test` platform matrix explicit:
    - `main`: `ubuntu-latest`, `macos-latest`, `windows-latest`
    - PRs / non-`main`: `ubuntu-latest` only

- **macOS native build gating**
  - Gate `build-rolldown-macos` behind `github.ref_name == 'main'`

- **macOS Node job gating**
  - Gate `node-test-macos` behind `github.ref_name == 'main'`
  - Gate `node-dev-server-test-macos` behind `github.ref_name == 'main'`

- **Workflow shape**
  - Keep Ubuntu PR coverage unchanged
- Mirror the existing Windows-on-`main` behavior instead of introducing
a separate policy path

```yml
strategy:
  matrix:
    target: ${{ github.ref_name == 'main'
      && fromJSON('["ubuntu-latest","macos-latest","windows-latest"]')
      || fromJSON('["ubuntu-latest"]') }}
```
