refactor: reorganize imports and improve code readability across components and libraries

- Reordered and grouped imports in Editable.tsx for better clarity.
- Simplified function definitions and removed unnecessary line breaks.
- Enhanced markdown parsing in parseIssue.ts to handle case insensitivity and BOM.
- Improved PDF generation logic in generatePdf.ts for cleaner code.
- Added unit tests for parseIssue function to ensure proper markdown parsing.
- Updated Vite configuration to include test environment settings.
- Introduced Biome configuration for code formatting and linting.
- Cleaned up CSS styles for consistency and readability.
