Refactor syncback process to improve clean mode handling and directory management

- Removed the ensure_project_paths_exist function, streamlining the syncback process by directly managing directory creation and cleanup within the syncback command.
- Enhanced error handling for sourcemap generation, logging warnings when clean mode removes directories that only contain meta files.
- Updated the logic for middleware selection in clean mode to better handle directory and script transitions based on the filesystem structure.
- Added utility functions to ensure base project directories exist before syncback, addressing the need for directory structure in clean mode.
- Improved test coverage for clean mode scenarios, ensuring that directory existence checks are performed and documented.
