Enhance provider packaging and CUDA download functionality

- Added support for packaging provider archives in the release workflow, creating platform-specific zip and tar.gz files for distribution.
- Updated the `.gitignore` to exclude `.spec` files.
- Introduced a new `CudaDownloadSection` component to manage CUDA downloads, including progress tracking and error handling.
- Refactored provider download logic to handle archive extraction and cleanup after download.
- Improved subprocess output handling in the provider manager for better logging and error reporting.
