Refactor/default command: updated default tool call command

[rohansen856]

This pull request improves the user experience for providing author information by automatically fetching the user's name and email from their Git configuration, and refactors the argument handling logic accordingly. It also introduces new utilities for reading Git config files cross-platform and removes the previous "help request" detection logic.

Enhancements to argument handling and user experience:

• When prompting for missing name or email arguments, the application now tries to fetch defaults from the user's Git configuration (via git config or directly from .gitconfig), and displays these as suggested defaults in the prompt. (src/args.rs, src/utils/prompt.rs, src/utils/git_config.rs) [1] [2] [3]
• Added a new utility function prompt_with_default to prompt the user with a suggested default value, improving usability. (src/utils/prompt.rs)

Utilities for Git configuration:

• Introduced a new module git_config that provides cross-platform functions to retrieve the user's Git name and email, including direct parsing of .gitconfig files. (src/utils/git_config.rs, src/utils/mod.rs) [1] [2]

Refactoring and cleanup:

• Removed the is_help_request logic and all related test cases, simplifying how the CLI determines when to prompt for arguments. (src/args.rs, src/main.rs, tests/integration_tests.rs) [1] [2] [3] [4] [5] [6]

Testing improvements:

• Added comprehensive tests for the new Git config parsing and cross-platform home directory detection logic. (src/utils/git_config.rs)
• Updated prompt utility tests to cover prompt_with_default. (src/utils/prompt.rs)

The gitconfig parser doesn't handle inline comments correctly. It includes the comment as part of the value instead of stripping it. The parser should split on '#' or ';' and only use the part before the comment.

Using assert!(true) is a no-op assertion that doesn't test anything meaningful. Consider removing this assertion or replacing it with a more specific test that validates the functions don't panic.

Suggested change

assert!(true);
