Display session ID in terminal tab title

Feature Request

When running multiple Claude Code sessions simultaneously, there's no way to identify which session is which from the terminal tab.

Problem:

• Power users often have 4+ Claude Code sessions open at once
• Each session is a UUID (e.g., 2f1b3084-b39d-4923-8731-0f37048e533b)
• Terminal tabs all show the same title — you have to guess which is which
• The only way to identify sessions is to dig through ~/.claude/projects/ and inspect JSONL files

Proposed Solution:
Display the session ID (or a short hash of it) in the terminal tab title. For example:

• Claude Code [2f1b] or Claude Code #2f1b3084
• Even better: allow users to name sessions, shown in the tab title

Why this matters:

• Users managing complex projects across multiple sessions need to quickly switch between them
• Session IDs are already tracked internally — just surface them in the tab title
• Would pair well with session resume workflows

Environment:

• macOS Terminal / iTerm2 / VS Code terminal
• Claude Code CLI (Opus 4.6)
