chore: revert version to 0.4.9 (#509)

* Add success toast after saving diagram

* fix: correct save toast placement

* Changes made:
1. Added i18n support
2. Fixed the issue where the save toast was running only once

* fix: show toast after download completes, not when dialog opens

Move toast from handleDrawioSave (dialog open) to saveDiagramToFile
(after download). Also restore the duplicate-save guard that was removed.
