feat: Implement compatibility strategies for responses and chat endpoints

- Added `routeCompatibility.ts` to handle response compatibility for different endpoints.
- Introduced `chatEndpointStrategy.ts` to manage chat endpoint recovery and downgrading logic.
- Created tests for chat formats and input file handling in `chatFormatsCore.test.ts` and `inputFile.test.ts`.
- Developed `endpointCompatibility.ts` to define compatibility checks and header building for various endpoints.
- Implemented protocol lifecycle management in `protocolLifecycle.ts` and corresponding tests in `protocolModel.test.ts`.
- Enhanced tooltip functionality with a new `TooltipLayer` component and associated tests.
- Refactored existing components to improve tooltip handling and ensure proper rendering in the application.
