Implement a TUI [interactive installer]

[M9nx]

Description:

Introduce a text-based interactive UI similar to Laravel’s installer. The TUI should guide users through:

Choosing batch size for chunk processing.
Selecting the embedding model.
Optionally, checking system resources and suggesting defaults.

Benefits:

• Improves user experience, especially for beginners.
• Makes configuration intuitive and avoids runtime errors.
• Provides a clear setup workflow similar to popular frameworks.
