v0.28.0

🆕 New Features

A lot of work done on Demo. The most important is that we are web now!

— How to try it:

1. Open the web demo and pick an example:
   • bipartite.json
   • tree_binary.json
2. Tweak Layout → Force-Directed/Hierarchical and play with Animation/Forces.
3. Click Export (top of the right panel) → choose “Include Layout” and/or “Node Positions”, then save to File or copy to Clipboard.
4. To import, go to the Import/Load tab → “Open” (or drag & drop a JSON file into the graph area). Your uploads appear under “User Uploads”.
5. On web, use Share to copy a deep link to the selected example.

• More useful keybindings were added (fit to screen (once), pan to graph)
• File import and export — planned to migrate to egui_graphs core in upcoming releases

Notes:

• New import/export features are in the demo UI only (not yet in the egui_graphs crate). Core support is planned.
• Positions are optional on import; if missing, nodes are placed in a circle initially.
