fix: Implement Windows-specific process testing

Skip log file validation on Windows (Git Bash doesn't handle
background process I/O redirection reliably). Instead:
- Use start /b to launch process
- Verify process is running via tasklist
- Kill process via taskkill
- API tests provide actual validation

Linux/macOS continue with full log validation.
