Add Stream chat integration as optional template feature

[tyaga001]

Is your feature request related to a problem? Please describe.
Next-Forge currently lacks built-in chat/messaging capabilities, requiring developers to either build chat features from scratch or integrate third-party solutions manually. This increases development time and complexity when building social/collaborative apps with Next.js.

Describe the solution you'd like
Add Stream Chat (https://getstream.io/chat/sdk/react/) as an optional template integration that developers can select during project setup.

This would provide:

1. Ready-to-use React chat components with TypeScript support:

• Message lists with UI virtualization
• Channel management
• Rich message input with file uploads
• Threading & reactions
• Real-time updates

2. Example implementations for everyday use cases:

• Social messenger (WhatsApp style): https://getstream.io/chat/demos/messaging/
• Team chat (Slack style): https://getstream.io/chat/demos/team/
• Live stream chat: https://getstream.io/chat/demos/livestream/

3. Pre-configured integration with:

• Next.js App Router
• TailwindCSS styling
• Authentication
• TypeScript types

• GitHub: https://github.com/GetStream/stream-chat-react/

I'm happy to help create a POC.

@haydenbleasel, let me know if you like the idea, and I'm happy to help ship it.

@tyaga001 Great idea! I'm thinking since this is quite app-specific we should make a Recipe for it (re: #293). Are you open to helping write that up?

@haydenbleasel sounds good; let me check with the team and get back to you asap.
