chore: streamline export by updating .gitattributes (#35)

Update .gitattributes to exclude unnecessary files from distribution archives, reducing package size for end-users.

Changes include:
- Rearrange existing rules for better organization
- Add 'sweep.yaml' and 'updates.sh' to export-ignore list

This aims to optimize the deployment process and provide a more lightweight package for users by ignoring non-essential files during the export phase.
