## TL;DR
This PR addresses text wrapping issues in the todo status bar while bundling several stability fixes, linting improvements, and dependency cleanup.

## What changed?
- **Todo display**: Prevent text wrapping in the status bar for long task names
- **Code quality**: Resolved all biome lint warnings and type safety issues
- **Dependencies**: Removed unused code, exports, and dependencies identified by knip
- **App updates**: Fixed pending app updates to install on app quit
- **Image handling**: Added image downscaling for clipboard paste operations
- **Branching workflow**: Improved branch creation flow to work off trunk without prefix UI
- **Prompt handling**: Fixed mode switching newline handling in prompt requests
- **Accessibility**: Enhanced custom permission prompt to properly support multiline text

I only made changes to the todo line wrapping and added a story for the todo. We're probably passing the wrong git history/context into the prompt for generating the PR title and description
