fix: Correct all platform-specific test failures

- Skip execution tests for ARMv7 (cannot run on x64 runner)
- Fix macOS stat command format (-f%z not -f%)
- Fix Windows Start-Process parameters
- Fix API test to validate JSON structure properly
- Add can_execute matrix flag for cross-compiled binaries
