Allow users to set custom terminal tab titles

Problem Statement

Claude Code auto-generates terminal tab titles from conversation content (e.g., "Backend change safety", "Spot Check Metrics"). There is no way for users to set or override these titles.

When running multiple Claude Code sessions in parallel, the auto-generated titles are often unhelpful — they change as the conversation evolves and don't reflect how the user thinks about each session
(e.g., "PR Review", "Frontend Dev", "Debugging Auth").

## What I tried

• /rename — changes the session name (shown in /resume) but does not update the terminal tab title
• name-tab via shell escape sequences (printf '\e]1;%s\a') — Claude Code immediately overwrites any externally set tab title
• --name flag — does not exist despite appearing in some documentation references

Why this matters

Power users run 4-8 Claude Code tabs simultaneously. Without custom titles, the only way to find the right tab is to click through each one. Custom titles would make parallel sessions practical.
```

Proposed Solution

## Proposed solution

A --name or --tab-title CLI flag that sets the terminal tab title and keeps it fixed:

```bash
claude --name "PR Review"

And a /rename update so it also changes the terminal tab title mid-session, not just the internal session name.
