feat: integrate custom features for smart context management

- Added a new integration script to manage custom features related to smart context.
- Implemented handlers for smart context operations (get, update, clear, stats) in ipc.
- Created a SmartContextStore class to manage context snippets and summaries.
- Developed hooks for React to interact with smart context (useSmartContext, useUpdateSmartContext, useClearSmartContext, useSmartContextStats).
- Included backup and restore functionality in the integration script.
- Validated integration by checking for custom modifications and file existence.
