[UX] Missing “Back” from chat to home (only way out is “New chat”)

What version of the VS Code extension are you using?

Codex Version 0.5.20

What subscription do you have?

Pro subscription

Which IDE are you using?

Visual Studio Code – Insiders 1.106.0-insider

What platform is your computer?

Microsoft Windows NT 10.0.26120.0 x64

What issue are you seeing?

The chat view in the Codex panel no longer has a Back control to return to the home/Recent list. The only visible escape is "New chat", which is non-discoverable and misleading (users expect it to create a new thread, not navigate “home”). This breaks navigation flow and muscle memory

What steps can reproduce the bug?

1. Open the Codex panel and click any existing chat
2. Try to go back to the home/Recent view
3. Notice there is no Back arrow near the title; the only visible way out is "New chat"

What is the expected behavior?

• A clear Back button in the chat header (or breadcrumbs like Codex / Recent / Chat)
• New chat should strictly create a new conversation, not act as navigation (no Recent chat
