feat: Add auto-dismiss functionality for Init Script Indicator

This commit introduces an auto-dismiss feature for the Init Script Indicator, enhancing user experience by automatically hiding the indicator 5 seconds after the script completes. Key changes include:

1. **State Management**: Added `autoDismissInitScriptIndicatorByProject` to manage the auto-dismiss setting per project.
2. **UI Components**: Updated the WorktreesSection to include a toggle for enabling or disabling the auto-dismiss feature, allowing users to customize their experience.
3. **Indicator Logic**: Implemented logic in the SingleIndicator component to handle auto-dismiss based on the new setting.

These enhancements provide users with more control over the visibility of the Init Script Indicator, streamlining project management workflows.
