fix: migrate playground to AI SDK v6 beta and resolve TypeScript errors

- Update @ai-sdk/react to v3.0.0-beta.131 for compatibility with AI SDK v6 - Fix tool execute method calls with type assertions in API routes - Update chat components to use UIMessage types from AI SDK - Move body option into DefaultChatTransport constructor - Remove deprecated onResponse option from useChat hook - Remove unused isCoreTool type guard function - Fix Button variant from 'primary' to 'default' Resolves all TypeScript compilation errors and build passes successfully. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
