This pull request introduces several improvements to Vue reactivity and
user experience in the graph node and widget system. The main focus is
on ensuring that changes to node and widget data reliably trigger
updates in Vue components, improving drag-and-drop support for nodes,
and enhancing widget value handling for better compatibility and
reactivity.
**Vue Reactivity Improvements:**
* In `useGraphNodeManager.ts`, node data updates now create a completely
new object and add a timestamp (`_updateTs`) to force Vue's reactivity
system to detect changes. Additionally, node data is re-set on the next
tick to guarantee component updates.

* Widget value composables (`useWidgetValue` and related helpers) now
accept either a direct value or a getter function for `modelValue`, and
always normalize it to a getter. Watches are updated to use this getter
for more reliable reactivity.

* In `useImageUploadWidget.ts`, widget value updates now use a new
array/object to ensure Vue detects the change, especially for batch
uploads.
**Drag-and-Drop Support for Nodes:**
* The `LGraphNode.vue` component adds drag-and-drop event handlers
(`dragover`, `dragleave`, `drop`) and visual feedback (`isDraggingOver`
state and highlight ring) for improved user experience when dragging
files onto nodes. Node callbacks (`onDragOver`, `onDragDrop`) are used
for custom validation and handling.

**Widget and Audio Upload Handling:**
* In `uploadAudio.ts`, after uploading an audio file, the widget's
callback is manually triggered to ensure Vue nodes update. There is also
a commented-out call to mark the canvas as dirty for potential future
refresh logic.

These changes collectively improve the reliability and responsiveness of
UI updates in the graph node system, especially in scenarios involving
external updates, drag-and-drop interactions, and batch widget value
changes.

## 📋 Overview
Implemented a new Media Assets sidebar tab in ComfyUI for managing
user-uploaded input files and generated output files. This feature
supports both local and cloud environments and is currently enabled only
in development mode.
## 🎯 Key Features
### 1. Media Assets Sidebar Tab
- **Imported** / **Generated** files separated by tabs
- Visual display with file preview cards
- Gallery view support (navigable with arrow keys)
### 2. Environment-Specific Implementation
- **`useInternalMediaAssets`**: For local environment
- Fetches file list via `/files` API
- Retrieves generation task execution time via `/history` API
- Processes history data using the same logic as QueueSidebarTab
- **`useCloudMediaAssets`**: For cloud environment
- File retrieval through assetService
- History data processing using TaskItemImpl
- Auto-truncation of long filenames over 20 characters (e.g.,
`very_long_filename_here.png` → `very_long_...here.png`)
### 3. Execution Time Display
- Shows task execution time on generated image cards (e.g., "2.3s")
- Calculated from History API's `execution_start` and
`execution_success` messages
- Displayed at MediaAssetCard's duration chip location
### 4. Gallery Feature
- Full-screen gallery mode on image click
- Navigate between images with keyboard arrows
- Exit gallery with ESC key
- Reuses ResultGallery component from QueueSidebarTab
### 5. Development Mode Only
- Excluded from production builds using `import.meta.env.DEV` condition
- Feature in development, scheduled for official release after
stabilization
