## Summary by CodeRabbit
* **New Features**
* DOM rendering added for groups, mind maps and connectors so group
titles/outlines and mindmap connectors are visible on canvas.
* Shapes now support right-to-left text with proper vertical alignment.
* **Improvements**
* Connector labels scale with viewport zoom for crisper display.
* Group-related selections (including nested groups) now update visuals
consistently.
* **Performance**
* Reduced DOM churn and fewer redraws during rendering and selection
changes.
* **Refactor**
* Renderer import/export surfaces consolidated with no user-facing
behavior changes.

### 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.
### 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
- **New Features**
- Added interaction extensions for edgeless variants of attachment, bookmark, edgeless text, embedded docs, images, notes, frames, AI chat blocks, and various embed blocks (Figma, GitHub, HTML, iframe, Loom, YouTube).
- Introduced interaction extensions for graphical elements including connectors, groups, mind maps, shapes, and text, supporting constrained resizing and rotation disabling where applicable.
- Implemented a unified interaction extension framework enabling configurable resize and rotate lifecycle handlers.
- Enhanced autocomplete overlay behavior based on selection context.
- **Refactor**
- Removed legacy resize manager and element-specific resize/rotate logic, replacing with a centralized, extensible interaction system.
- Simplified resize handle rendering to a data-driven approach with improved cursor management.
- Replaced complex cursor rotation calculations with fixed-angle mappings for resize handles.
- Streamlined selection rectangle component to use interactivity services for resize and rotate handling.
- **Bug Fixes**
- Fixed connector update triggers to reduce unnecessary updates.
- Improved resize constraints enforcement and interaction state tracking.
- **Tests**
- Refined end-to-end tests to use higher-level resize utilities and added finer-grained assertions on element dimensions.
- Enhanced mouse movement granularity in drag tests for better simulation fidelity.
- **Chores**
- Added new workspace dependencies and project references for the interaction framework modules.
- Extended public API exports to include new interaction types and extensions.
