feat: Implement adapter runtime state management and update handling

- Added support for adapter runtime state updates in the PluginRunnerSupervisor.
- Introduced new payload classes: AdapterStateUpdatePayload and AdapterStateUpdateResultPayload for handling state updates.
- Implemented methods to bind and unbind routes based on adapter connection status.
- Enhanced the NapCat adapter to report connection state and manage runtime state.
- Added tests for adapter runtime state synchronization and database session behavior in the statistic module.
- Updated existing methods to ensure proper handling of adapter state and route bindings.
