feat: Implement Custom ImGui Assertion Handler to Enhance Stability

- Added a custom assertion handler for ImGui to log assertion failures instead of crashing the application.
- Implemented a mechanism to back up and reset ImGui workspace settings after multiple assertion failures.
- Updated the window creation process to set the custom assertion handler conditionally based on build configuration.
- Enhanced the welcome screen to truncate project names for better display in the UI.
