fix: resolve module structure issues by separating CLI and git modules

- Removed duplicated git module code from cli.rs
- Created dedicated git.rs module with GitRepo, StagedChanges, ChangedFile, FileStatus definitions
- Updated all modules (analyzer, generator, prompt) to import from super::git
- Fixed module organization to resolve compilation errors
