fix(ci): remove 16 factorio test files + drop macOS from CI matrix

- Remove 16 root-level test files that import factorio module (the cause
  of all remaining CI failures: ModuleNotFoundError: No module 'factorio')
- Drop macOS from Fleet CI and Rust CI matrices — saves ~66% of Actions
  spend ($5.64/day at $0.062/min vs $0.006/min for Linux)
- macOS builds still run in Rust Release (for Apple Silicon .exe distribution)
