### TL;DR
Added DOM-based renderer for connector elements in the AFFiNE editor.
### What changed?
- Created a new DOM-based renderer for connector elements that uses SVG
for rendering
- Implemented `ConnectorDomRendererExtension` to register the DOM
renderer for connector elements
- Added support for rendering connector paths, endpoints (arrows,
triangles, circles, diamonds), stroke styles, and labels
- Registered the new DOM renderer extension in the connector view setup
- Added comprehensive tests to verify DOM rendering functionality
### How to test?
1. Enable the DOM renderer flag in the editor
2. Create connector elements between shapes or with fixed positions
3. Verify that connectors render correctly with different styles:
- Try different stroke styles (solid, dashed)
- Test various endpoint styles (Arrow, Triangle, Circle, Diamond)
- Add text labels to connectors
4. Check that connectors update properly when connected elements move
5. Verify that connectors are removed when deleted
### Why make this change?
The DOM-based renderer provides an alternative to the Canvas-based
renderer, offering better accessibility and potentially improved
performance for certain use cases. This implementation allows connectors
to be rendered as SVG elements within the DOM, which can be more easily
inspected, styled with CSS, and interacted with by assistive
technologies.

Close [BS-3426](https://linear.app/affine-design/issue/BS-3426/frame-修改背景色后不能撤销)
This PR fixes the issue where the color change of edgeless blocks could not be undone/redone, including notes, edgeless-text, and frames. It also addresses the problem of a tiny shape being unexpectedly retained on the canvas. The key changes are:
- Removal of `transact` from the `pop` method of edgeless elements.
- Refactoring of `onPickColor` for all edgeless elements and blocks to better control the lifecycle of custom color property changes.
- Addition of the missing custom background color feature for notes.
- Addition of undo/redo color tests for notes, frames, and edgeless-text.

- **Tests**
- Introduced new end-to-end tests to verify undo/redo functionality for color changes in frames, notes, and text blocks.
- **Refactor**
- Streamlined color picker event handling for better maintainability and consistency across toolbars and style panels.
- Updated style panel structure and event handling for improved interaction and state management.

### Changed
This pr split the old `edgeless-selected-rect` into four focused modules:
- `edgeless-selected-rect`: Provide an entry point for user operation on view layer only, no further logic here.
- `GfxViewInteractionExtension`: Allow you to plug in custom resize/rotate behaviors for block or canvas element. If you don’t register an extension, it falls back to the default behaviours.
- `InteractivityManager`: Provide the API that accepts resize/rotate requests, invokes any custom behaviors you’ve registered, tracks the lifecycle and intermediate state, then hands off to the math engine.
- `ResizeController`: A pure math engine that listens for pointer moves and pointer ups and calculates new sizes, positions, and angles. It doesn’t call any business APIs.
### Customizing an element’s resize/rotate behavior
Call `GfxViewInteractionExtension` with the element’s flavour or type plus a config object. In the config you can define:
- `resizeConstraint` (min/max width & height, lock ratio)
- `handleResize(context)` method that returns an object containing `beforeResize`、`onResizeStart`、`onResizeMove`、`onResizeEnd`
- `handleRotate(context)` method that returns an object containing `beforeRotate`、`onRotateStart`、`onRotateMove`、`onRotateEnd`
```typescript
import { GfxViewInteractionExtension } from '@blocksuite/std/gfx';
GfxViewInteractionExtension(
flavourOrElementType,
{
resizeConstraint: {
minWidth,
maxWidth,
lockRatio,
minHeight,
maxHeight
},
handleResize(context) {
return {
beforeResize(context) {},
onResizeStart(context) {},
onResizeMove(context) {},
onResizeEnd(context) {}
};
},
handleRotate(context) {
return {
beforeRotate(context) {},
onRotateStart(context) {},
onRotateMove(context) {},
onRotateEnd(context) {}
};
}
}
);
```

## 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.
No user-facing features or behaviors have changed.

### TL;DR
For canvas elements, this PR adds placeholders during zooming operations to improve performance.
### What changed?
- Implemented placeholder rendering during zooming operations in the canvas renderer, but not only DOM.
- Added a `forceFullRender` property to the `GfxCompatibleInterface` to allow elements to opt out of placeholder rendering
- Set `forceFullRender = true` for connectors to ensure they always render properly, even during zooming
- Connected the turbo renderer to the viewport's zooming state to automatically switch between full and placeholder rendering
### Why make this change?
Rendering complex elements during zooming operations can cause performance issues and make the UI feel sluggish. Rendering connector label also leads to high cost DOM `set font` delays.
The turbo renderer improves performance by displaying simple placeholders for elements during zooming, while still rendering critical elements like connectors fully. This creates a smoother user experience while maintaining essential visual information.
<!-- This is an auto-generated comment: release notes by coderabbit.ai -->
## Summary by CodeRabbit
- **New Features**
- Introduced a feature-flag-controlled "turbo" rendering mode that displays placeholder graphics during zooming for improved performance.
- Added the ability to override placeholder rendering for specific elements, ensuring full rendering when required.
- **Bug Fixes**
- Enhanced rendering logic to ensure connectors always render fully, even during zoom operations.
- **Documentation**
- Updated API documentation to reflect new properties related to rendering behavior.
- **Tests**
- Improved tests to verify correct rendering behavior for connectors.

### Changed
Moved connector label moving logic from `default-tool` to connector view.
#### Other infrastructure changes:
- Gfx element view now can handles drag events
- Added `context.preventDefault()` support to bypass built-in interactions in extension
- Handle the pointer events in element view will bypass the built-in interactions automatically
> The built-in interactions include element dragging, click selection, drag-to-scale operations, etc.
### Change
- Rename `ElementTransformManager` -> `InteractivityManager`
- Now you can `event.on` and `action.onXXX` method to extend interactivity behaviour. The old approach of overriding methods directly is deprecated.
continue #10824
### Changed
- Moved double-click-to-edit behavior from the default tool to individual model views
- Introduced `onSelected` callback interface in gfx view components to allows developers to override default selection logic
