What's Wrong?

Bug Description

When using the /clear command, the new session created gets titled "/clear" instead of
a meaningful title. This makes it impossible to find the session later using /resume,
which lists sessions by title.

## Actual Behavior

The session is titled "/clear" in the /resume session list, making it impossible to
identify or distinguish from other sessions that were also cleared.

## Workaround

Avoid /clear — instead close the terminal and start a new claude session manually.

## Environment

• OS: Linux (Ubuntu)
• Claude Code version: (provjeri sa claude --version)

What Should Happen?

Expected Behavior

After /clear, the session should either:

• Retain the previous session title, or
• Generate a new meaningful title based on the first user message after clearing, or
• At minimum, not use the command name "/clear" as the title

Steps to Reproduce

## Steps to Reproduce

1. Start a Claude Code session in a project
2. Run /clear to clear the conversation context
3. Continue working in the session
4. In a new terminal, run claude and use /resume
5. The session appears in the list as "/clear" — not recognizable
