### Problem
●In edgeless mode, when the `note-edgeless-block` is scaled below 100%,
its outer dimension becomes larger than its content region. This extra
invisible region will block some user interactions such as clicks and
hovers on editing elements underneath.

/>
●The following video demonstrates this issue:

### Solution
●The root cause is that `transform: scale(...)` CSS property (which
implements the scale) is currently applyed to its **inner root element**
instead of itself, and the solution is to move this CSS property to the
proper place.
### After
●The video below shows the behavior after this fix.

## Summary by CodeRabbit
* **Refactor**
* Centralized CSS scaling for graphics and edgeless note blocks into
dedicated public methods; rendering now uses these methods instead of
inline transform calculations.
* **Tests**
* Updated end-to-end checks to read scale directly from the edgeless
note element and use a more flexible transform-matching pattern.

### 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.
