fix: Add separate workflow steps for each OS

This commit restructures the GitHub Workflow to use separate, conditional steps for each operating system (Linux, macOS, and Windows). This allows for platform-specific commands and better isolation for debugging.

- The Linux step continues to use `xvfb-run`.
- The macOS step now runs the client directly.
- The Windows step uses `gradlew.bat` and `findstr` for compatibility with the Windows command-line environment.

This change is intended to resolve the failures observed on macOS and Windows by tailoring the execution environment to each platform's requirements.
