Feature Request: Add /clear command to clear screen

Summary

Currently, the /new command starts a fresh conversation but does not clear the terminal screen. The previous chat history remains visible, which can be visually cluttered.

Requested Feature

Add a /clear command (or enhance /new) to:

1. Start a new conversation (current behavior)
2. Clear the terminal screen (new behavior)

Comparison with Similar Tools

| Tool | Command | Clears Screen | New Session |
|------|---------|---------------|-------------|
| Claude Code | /clear | ✅ Yes | ✅ Yes |
| Codex CLI | /new | ❌ No | ✅ Yes |

Current Workaround

Users can manually press Ctrl+L after /new to clear the screen, but this requires two steps.

Suggested Implementation

Option A: Add a new /clear command that does both
Option B: Add a --clear flag to /new (e.g., /new --clear)
Option C: Make /new clear the screen by default
