Summary

Fixes #575

This PR prevents unnecessary Colorama initialization when Python Fire runs inside Git Bash on Windows.

Git Bash already supports ANSI escape sequences, so initializing Colorama can cause redundant output wrapping and interfere with terminal colors.

Changes

• Detect Git Bash environments using the MSYSTEM environment variable.
• Skip Colorama initialization for MinGW and MSYS terminals.
• Preserve existing behavior for other Windows terminals.
• Add unit tests covering Git Bash detection, standard Windows initialization, and behavior when Colorama is unavailable.

Testing

Added focused unit tests for the affected behavior.

The full test suite has not yet been run locally. CI validation is requested.
