Use MarkerType enum instead of `as any` cast in store.ts

[johnkozaris]

Problem

In store.ts line 575, flashMessageEdge creates an edge with:

markerEnd: { type: 'arrowclosed' as any, color: getAccentColor(), width: 16, height: 16 },

The as any cast bypasses TypeScript's type checking for the React Flow MarkerType enum. This is fragile — if React Flow changes the marker type values or API, the error will be silently swallowed.

Fix

Import and use the MarkerType enum from @xyflow/react:

import { MarkerType } from '@xyflow/react';

// ...
markerEnd: { type: MarkerType.ArrowClosed, color: getAccentColor(), width: 16, height: 16 },
