Pull Request Overview
This PR fixes three critical issues: corrects Git status parsing, prevents command injection in shell exports, and improves the interactive setup wizard with validation, testing, and progress tracking.
- Refine parsing in
getUnstagedChangesto only capture truly unstaged modifications - Escape and validate user inputs for API key and editor command to close injection vectors
- Enhance
gitlift initwith real API/CLI/Git tests, progress summaries, and additional language options

- Add unit tests for the API key and editor command validation logic to ensure that edge cases and all validation branches produce the expected messages.

Using trimmedLine (which has no leading spaces) with .startsWith(" M") will never match. You should check the raw line or inspect characters by index before trimming, e.g., if (line.startsWith(' M')).
| if (trimmedLine.startsWith(" M")) { | |
| // Only files modified in working tree but not staged | |
| unstagedModifiedFiles.push(trimmedLine.substring(2).trim()); | |
| } else if (trimmedLine.startsWith("??")) { | |
| untrackedFiles.push(trimmedLine.substring(2).trim()); | |
| if (line.startsWith(" M")) { | |

| } else if (line.startsWith("??")) { | |
| untrackedFiles.push(line.substring(2).trim()); |

Consider using a dedicated shell-escaping library (e.g., shell-escape) instead of a custom replace to reliably handle all special characters and fully mitigate command injection risks.

[nitpick] Throwing on a missing API key stops the rest of the configuration tests (GitHub CLI, Git). Consider issuing a warning and continuing so users get full feedback on all checks.
Fix Git status parsing logic, address command injection vulnerabilities, and enhance the setup wizard.
The Git status parsing bug incorrectly identified staged files as unstaged. The command injection vulnerability allowed unsanitized user input to be interpolated into shell commands. The setup wizard enhancements include improved API key validation, actual API call testing, better error handling, progress tracking, and additional language options, significantly improving the initial user experience and security.
