GitAuto: [FEATURE] Add Command to Set Environment Variable

[gitauto-ai]

Resolves #38

What is the feature

The feature is a new command for a .NET tool project that allows users to set environment variables via the command-line interface (CLI). The command will accept two arguments: the variable value (required) and an optional target specifying where the variable should be set (User or Machine scope).

Why we need the feature

This feature is needed to simplify environment setup, especially in CI/CD pipelines or automated scripts. It provides flexibility by allowing users to specify the target scope (User or Machine) for the environment variable, making it easier to manage environment configurations programmatically.

How to implement and why

1. Create a new command in the CLI tool:

   • Implement a command that parses input arguments to extract the environment variable name, value, and target scope.
   • Use the Environment.SetEnvironmentVariable method to set the variable, with the target defaulting to User if not specified.

2. Handle input validation:

   • Ensure the input format is correct (e.g., VAR_NAME=value).
   • Validate the target scope to be either User or Machine.

3. Implement platform-specific logic:

   • Since setting environment variables is platform-dependent, ensure the feature is implemented for platforms that support it, such as Windows using EnvironmentVariableTarget.

4. Provide feedback to the user:

   • Output a confirmation message indicating the environment variable has been set, including the target scope.

5. Update documentation:

   • Add usage examples and detailed instructions in the README or relevant documentation files.

About backward compatibility

This feature is an addition and does not affect existing functionality, so backward compatibility is maintained. The default behavior of setting the environment variable for the current user ensures that existing workflows remain unchanged unless explicitly modified by the user.
