Version 0.9.5

[rsgalloway]

This pull request introduces several improvements and fixes for cross-platform compatibility, especially for Windows, refines environment variable handling, and enhances test coverage and reliability. The most significant changes are grouped below.

Windows Support and Path Handling:

• Added a Windows-friendly make.bat script to simplify building, testing, and installing the project on Windows systems.
• Updated path handling logic and tests to consistently use uppercase drive letters for Windows paths and UNC-style paths (e.g., //tools/pipe) instead of drive letters, improving reliability and consistency across platforms. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Command Wrapper Improvements:

• Refactored CmdWrapper in wrapper.py to explicitly invoke cmd.exe with correct argument handling, ensuring robust execution of wrapped commands on Windows.
• Improved the logic in run_command to better detect shell types and handle variable expansion for Windows and Unix-like shells.

Testing and CI Enhancements:

• Added a GitHub Actions workflow (tests.yml) to run tests on Ubuntu, macOS, and Windows, increasing CI coverage.
• Applied platform-specific test skips and updated test root paths for improved reliability and correctness in the test suite. [1] [2] [3] [4]

CLI and Usability Improvements:

• Enhanced the CLI shell launch message to provide clear exit instructions based on the detected shell (e.g., cmd, powershell, bash). [1] [2]
• Improved imports and quiet mode handling in the CLI for better maintainability and user experience. [1] [2]

Version Bump:

• Updated the package version to 0.9.5 in both setup.py and lib/envstack/__init__.py to reflect these changes. [1] [2]
