<!-- This is an auto-generated comment: release notes by coderabbit.ai -->

## Summary by CodeRabbit

- **New Features**
  - Introduced feature flag synchronization for enhanced control over feature availability.
  - Added new configuration options for store management, allowing initialization and feature flag setup.

- **Improvements**
  - Updated how store extensions are accessed throughout the app for more robust initialization and configuration.
  - Enhanced workspace entities to support feature flag services, improving flexibility for workspace-specific features.
  - Centralized configuration of storage implementations for Electron environments.

- **Refactor**
  - Simplified editor module by removing direct feature flag synchronization logic.
  - Streamlined imports and configuration for storage modules, especially in Electron-based apps.

- **Bug Fixes**
  - Ensured consistent retrieval of store extensions across various modules and platforms.
