[FEATURE] Reset terminal tab title after /clear command

Problem Statement

After running /clear to reset the conversation, the terminal tab title (in iTerm2 and other terminals that support escape sequences) retains the previous conversation topic. This breaks the expectation of a "fresh start" after clearing.

Proposed Solution

Send a terminal escape sequence to reset the tab title after /clear completes. Something like:

\033]0;Claude Code\007

This would reset the title to a generic "Claude Code" or similar default.

Alternative Solutions

Users can manually reset the title with:

echo -ne "\033]0;Claude Code\007"

But this shouldn't be necessary after using /clear.

Priority

Low - Minor UX polish

CLI commands and flags

Use Case Example

1. Working on a task, tab title updates to "Note Creation Abuse"
2. Run /clear to start fresh
3. Tab still shows "Note Creation Abuse" even though conversation is cleared
4. Expected: Tab title resets to "Claude Code" or similar default

Additional Context

Tested in iTerm2 on macOS. The title is set correctly during conversations, just not reset on clear.
