- Introduced a new IdeationService to manage brainstorming sessions, including idea creation, analysis, and conversion to features.
- Added RESTful API routes for ideation, including session management, idea CRUD operations, and suggestion generation.
- Created UI components for the ideation dashboard, prompt selection, and category grid to enhance user experience.
- Integrated keyboard shortcuts and navigation for the ideation feature, improving accessibility and workflow.
- Updated state management with Zustand to handle ideation-specific data and actions.
- Added necessary types and paths for ideation functionality, ensuring type safety and clarity in the codebase.
