- Introduced type-safe access methods for shared cache in the Main process, including `getShared`, `setShared`, `hasShared`, and `deleteShared`.
- Implemented `getAllShared` for initializing new Renderer windows with the complete shared cache state.
- Updated IPC communication to support bidirectional synchronization of shared cache between Main and Renderer processes.
- Enhanced cache management with absolute timestamps for TTL, ensuring precise expiration handling across windows.
- Added ready state tracking in Renderer for improved synchronization feedback during initialization.
- Refactored related documentation to reflect new features and usage patterns for shared cache.
- Refactored tests in MainTextBlock and ThinkingBlock to utilize the usePreference hook for managing user settings.
- Updated snapshots in DraggableVirtualList test to reflect changes in class names.
- Enhanced export tests to ensure proper handling of markdown formatting and citation footnotes.
- Mocked additional dependencies globally for improved test reliability.
