Show conversation title when in the conversation view

Describe the feature or problem you'd like to solve

I want to see what conversation I'm looking at in the CLI without going to /session to view it

Proposed solution

Either at the top here or the bottom, I'd like to see the name of the conversation. It would be very helpful to context switch between simultaneous conversations

(left side with branch/path redacted)

Example prompts or workflows

Running simultaneous conversations, whether within one terminal or multiple. It is hard to tell what the active conversation is about without typing /session to see the name.

Additional context

This could also be a good opportunity to augment the terminal title so I see "Copilot" instead of just "zsh"

CLI の会話ビューから始め、現在は会話名を公開している /session ビューと比較します。アクティブな会話がどこでレンダリングされるか、またターミナルタイトルが同じエントリーポイントの一部かどうかを確認します。表示中にアクティブな会話を識別でき、ターミナルタイトルの変更が選択したスコープと一致していれば完了です。
