Pull request overview
Adds a toast notification system to surface operational failures (e.g., clipboard and download actions) and wires it into the diagram editor UI.
Changes:
- Introduces a global toast store (
useToast) and UI renderer (Toaster) based on Radix Toast primitives. - Updates Mermaid export actions to show success/error toasts and expands unit tests to cover those cases.
- Adds a minimap toggle control button in the React Flow controls (currently duplicated—see review comments).
