## Summary by CodeRabbit
- **Refactor**
- Unified internal data access by replacing all references from `doc` to `store` across all components, blocks, widgets, and utilities. This affects how readonly state, block operations, and service retrieval are handled throughout the application.
- **Tests**
- Updated all test utilities and test cases to use `store` instead of `doc` for document-related operations.
- **Chores**
- Updated context providers and property names to reflect the change from `doc` to `store` for improved consistency and maintainability.

## Fix Shape Tool Issues
This PR addresses several issues with the shape and mindmap tools functionality in the editor:
1. **Fix text editing after mode switching**: Resolves an issue where users couldn't edit text in shapes after switching editor modes. The fix ensures the edgeless block is properly retrieved when double-clicking on a shape.
2. **Improve tool switching behavior**: Fixes issues with tool overlays not showing or being repeated when switching between tools. This includes:
- Properly handling tool overlay visibility
- Ensuring only one tool is active at a time when using keyboard shortcuts
- Adding proper cleanup when switching tools
3. **Add comprehensive tests**: Adds new test cases to verify:
- Shape creation with keyboard shortcuts
- Shape text editing after mode switching
- Tool switching behavior with keyboard shortcuts
