Expand CI Testing to Include Windows and macOS #159

Description

Currently, the CI pipeline for CodeEntropy only runs tests on Ubuntu-based systems. To ensure broader compatibility and reliability across platforms, we should expand our CI testing to include Windows and macOS environments.

Benefits

Adding cross-platform testing will:

• Help identify OS-specific bugs or dependency issues early.
• Ensure consistent behaviour for users on different operating systems.
• Improve confidence in the portability and robustness of the codebase.

Proposed Changes

• Update the CI configuration to include matrix builds for:
  • ubuntu-latest
  • windows-latest
  • macos-latest
• Review and resolve any platform-specific test failures or setup issues.
