Merge pull request #4842 from camilamacedo86/fix-alpha-generate-cleanup

🐛 (cli): Fixed an issue where `alpha generate` skipped files and directories beginning with a dot (e.g., `.github/`, `.env`, `.golangci.yaml`). These are now properly removed during cleanup, except `.git` and `PROJECT`, which are intentionally preserved.
