chore: remove unused shadcn/ui toast implementation

[Copilot]

The codebase contains an unused custom toast implementation from shadcn/ui while exclusively using the sonner library for toast notifications.

Changes

Removed 4 unused files:

• src/hooks/use-toast.ts - Custom toast hook
• src/ui/shadcn/components/ui/toast.tsx - Toast UI components (Radix primitives)
• src/ui/shadcn/components/ui/toaster.tsx - Toaster component wrapper
• src/ui/shadcn/components/ui/use-toast.ts - Duplicate toast hook

These files only referenced each other and had no imports elsewhere in the codebase. All toast functionality uses:

import { toast } from "sonner";
import { Toaster } from "sonner";
