Fix asset validation error in CI builds

- Remove specific binary file references from pubspec.yaml
- Add assets/bin directory creation step before binary download
- Ensure assets directory exists before Flutter commands
- Add .gitkeep file to maintain assets/bin directory structure

This fixes the 'No file or variants found for asset' error that was causing CI failures.
