# Update/Fix build workflow

- `macos-latest-xlarge` is no longer available. Switch to cheaper
runner: `macos-latest-xlarge` -> `macos-latest`
- Refactor build to run matrix job under Linux and macOS
- Tune caching GH caching
- Add junit and logger properties
- Downgrade Junit to 5.14.2
- Extract `ProcessBuilder` creation logic into helper functions
- Disable `StdioClientTransportTest` on windows temporary

## How Has This Been Tested?
CI

## Breaking Changes
Functionally - no. Outdated/broken TypeScript tests were disabled

## Types of changes
<!-- What types of changes does your code introduce? Put an `x` in all
the boxes that apply: -->
- [x] Bug fix (non-breaking change which fixes an issue)
- [x] CI Update

## Checklist
<!-- Go over all the following points, and put an `x` in all the boxes
that apply. -->
- [ ] I have read the [MCP
Documentation](https://modelcontextprotocol.io)
- [ ] My code follows the repository's style guidelines
- [ ] New and existing tests pass locally
- [ ] I have added appropriate error handling
- [ ] I have added or updated documentation as needed

## Additional context
GitHub actions workflows were blocked because the selected
"macos-latest-xlarge" runner, which is not available for the free
open-source plan. With "macos-latest" workflow works.
