chore: Enhance type safety and improve code consistency across components

- Added a new `typecheck` script in `package.json` for better type checking in the UI workspace.
- Refactored several components to remove unnecessary type assertions and improve type safety, particularly in `new-project-modal.tsx`, `edit-project-dialog.tsx`, and `task-progress-panel.tsx`.
- Updated event handling in `git-diff-panel.tsx` to use async functions for better error handling.
- Improved type definitions in various files, including `setup-view` and `electron.ts`, to ensure consistent usage of types across the codebase.
- Cleaned up global type definitions for better clarity and maintainability.

These changes aim to streamline the development process and reduce potential runtime errors.
