Git Clone Authentication for Private Repositories

- Uses 'git -c http.extraHeader=Authorization: Basic <base64>' for authentication
- Token is encoded as 'base64("x-access-token:TOKEN")' following GitHub's Basic Auth format
- Token is never stored in URL, git config, or project metadata
- 'GIT_TERMINAL_PROMPT=0' prevents interactive credential prompts
- Remote URL displayed in UI always has auth info stripped for security
