Feature Request: Streaming text output in CLI (typewriter effect like Claude Desktop)

Feature Request

Summary
Add an option to stream text output progressively in the Claude Code CLI,
similar to how Claude Desktop displays responses (typewriter/streaming effect).

Current Behavior
Claude Code CLI buffers the entire response and renders it all at once,
which can make it harder to read long responses as they appear suddenly.

Expected Behavior
An option (e.g., in settings.json or a CLI flag) to enable progressive
text streaming, where the response appears line by line or in chunks
as it is generated — similar to the experience in Claude Desktop.

Use Case

• Easier to follow long responses in real time
• More natural reading flow for conversational interactions
• Better UX for users coming from Claude Desktop

Suggested Implementation

• A toggle in settings.json (e.g., "streamingOutput": true)
• Or a CLI flag (e.g., --stream)
