double-clicking on their titles.

### Changes 🏗️

- **Added inline node title editing functionality:**
  - Users can now double-click on any node title to enter edit mode
  - Custom titles are saved on Enter key or blur, canceled on Escape key
- Custom node names are persisted in the node's metadata as
`customized_name`
  - Added tooltip to display full title when text is truncated

- **Modified node data handling:**
- Updated `nodeStore` to include `customized_name` in metadata when
converting nodes
- Modified `helper.ts` to pass metadata (including custom titles) to
custom nodes
  - Added metadata property to `CustomNodeData` type

- **UI improvements:**
  - Added hover cursor indication for editable titles
  - Implemented proper focus management during editing
  - Maintained consistent styling between display and edit modes
