[FEATURE] Desktop: session toolbar (terminal / panel / Browser) is unavailable until the first prompt is sent

Problem

In the Claude Code desktop app, when I start a new session the session toolbar icons (terminal, panel, Browser) are not present. They only appear after I send a first prompt and the session actually materializes.

This means that for any task where I already know I want the Browser pane — front-end work, UI review, anything against a local dev server — I have to send a throwaway prompt first just to unlock the toolbar, then open the Browser, then start the real work.

Settings → Claude Code → Browser has four controls:

• Browser tools (on)
• Open links in the built-in browser
• Keep cookies (Shared / Per session)
• Allowed sites

None of them control whether the Browser pane is visible when a session starts. Cmd+Shift+B / the Views menu also don't help before the session exists.

Steps to reproduce

1. Open the Claude Code desktop app.
2. Click New (or pick a project) to start a new session.
3. Look at the session toolbar.

Actual: no terminal / panel / Browser icons. The Browser pane cannot be opened.

Expected: the toolbar is present from the start, so the Browser pane can be opened before sending any prompt.

Proposed solution

Either of these would solve it:

1. Render the session toolbar as soon as a new session is opened, before the first message — so the Browser pane can be opened immediately.
2. Add a setting under Settings → Claude Code → Browser, e.g. "Open the Browser pane in new sessions", so it comes up automatically.

Option 2 is the one I'd personally use — for projects with a dev server defined in .claude/launch.json, the Browser is wanted on essentially every session, and opening it by hand each time is pure repetition.
